What Students Need Most When the Stakes Are High

Monday, June 4th, 2018

Written By: Jay Meadows, Chief Education Officer 

High stakes, end-of-year performance tasks on statewide tests have become the norm in recent years. These types of questions are designed to assess how well students can utilize their developing math skills to answer authentic—multi-step, complex problems that can be solved with a variety of strategies.

How do we prepare our students for these challenging tasks while—at the same time— ensure that we are utilizing the precious minutes in every class period and are not “teaching to the tests”? The answer lies in what we hope to accomplish in our math classrooms.

Math students in today’s changing world need to be able to able to calculate precisely and efficiently. Skill development remains a foundation in the math curriculum. However, students must also develop the ability to (1) utilize these computation skills as they work to solve complex problems, (2) reason effectively in finding efficient solutions, (3) communicate and (4) model their ideas and strategies utilizing the tools of mathematicians.

Students Need Practice

Exemplars has been creating rich and engaging performance tasks in mathematics for the purpose of instruction and assessment for the past 25 years. To master performance assessments, just as with any important skill, students need to practice. That practice time is only viable if the skills developed are relevant to their success outside of the classroom. In the 21st century, the skills needed for success include the ability to communicate effectively, collaborate within teams, and apply critical thinking to solve complex problems in new and creative ways.

By having students practice with rigorous problem-solving performance tasks, such as Exemplars, teachers can intentionally nurture these 21st-century skills while developing the math process standards NCTM has articulated as the foundation of strong mathematicians: Problem Solving, Reasoning and Proof, Communication, Connections and Representations.

Through rich problem solving, students are given the opportunities to work collaboratively in small teams, thus learning to communicate their ideas and strategies with others while listening to the explanations of their peers. Students can then bring their own ideas forward creatively, and efficiently work to solve these problems and develop persuasive arguments to explain their ideas to the whole classroom. This setting helps students develop the skills the 21st century requires.

Exemplars is the Perfect Supplement

Our collection of more than 800+ problem-solving performance tasks in mathematics present students with the opportunity to develop the skills of collaboration, communication, creativity and problem-solving.  Exemplars tasks have been classroom tested, and include student work samples that teachers and students can utilize to gain an understanding of what high-quality work actually looks like. Our material also provides standards-based assessment rubrics for teachers and students, detailed lesson planning sheets for each task, and differentiated problems.

What is a mathematical connection? Why are mathematical connections important? Why are they considered part of the Exemplars rubric criteria? And how can I encourage my students to become more independent in making mathematical connections?

The four-part blog series below explores mathematical connections and offers guidelines, strategies, and suggestions for helping teachers elicit this type of thinking from their students. We find many students enjoy making connections once they learn how to reflect and question effectively. As part of this series, student work will be examined at Grades 1, 3 and 5.

Understanding Mathematical Connections at the First Grade Level

Thursday, March 29th, 2018

Written By: Deborah Armitage, M.Ed., Exemplars Math Consultant

In today’s post, we’ll look at a first-grade student’s solution for the task, “Pictures on the Wall.” This anchor paper demonstrates the criteria for Problem Solving, Reasoning and Proof, Communication, Connections and Representation from the Exemplars assessment rubric. It also shows a solution that goes beyond arithmetic calculation and provides the evidence that a student can reflect on and apply mathematical connections. The beauty of mathematical connections is that they often begin with the other four rubric criteria. In other words, the Exemplars rubric provides multiple opportunities for a student to connect mathematically!

In this piece of student work, you’ll also notice that the teacher has “scribed” the student’s oral explanation. Scribing allows teachers to fully capture the mathematical reasoning of early writers.

This blog will offer tips for the type of instructional support a teacher may provide during this learning time as well as the type of support students may give each other. Teacher support may range from offering direct instruction to determining if a student independently included mathematical connections in her or his solution. After reading this post, give the task a try in your own classroom along with the Exemplars rubric. You may view other Exemplars tasks here.

First Grade Task: Pictures on the Wall

There are sixteen pictures on a wall. The art teacher wants to take all the pictures off the wall to put up new pictures. The art teacher takes seven pictures off the wall. How many more pictures does the art teacher have to take off the wall? Show all your mathematical thinking.

Dynamic Math Learning at The Phoenix School

Thursday, March 29th, 2018

Written By: Barbara McFall, Head of School

Extending Exemplars problem, "Park Play Area," to an irregular quadrilateral that will become a plan for one of our community’s potential park spaces … real-life math building on an Exemplars problem!

Fall is the time of year when my students begin pestering me for “real” word problems. They love solving problems that include the names of their classmates and using a collaborative experience in which they can bounce ideas off one another as they work through more complex problems. My go-to resource for problems that create mathematical thinkers of my students is Exemplars.

At The Phoenix School, for many years (first in paper form, now digital) Exemplars has been a vital component of our math program. No more memorization and regurgitation that flies in – and out! — of kids’ brains. Exemplars work solidifies concepts, which are the foundation of mathematical learning, and allows for multiple solutions as well as encouraging creative thinking. It has the flexibility that enables us to extend concepts on which we have been working … and it is so well organized that it is easy to determine which sets of problems we need to best showcase particular math concepts.

Working Exemplars problems requires students to do much more thinking than in traditional mathematical learning formats. It teaches them to analyze information and focus on what is most important in getting to the solution. Exemplars problems also encourage students to use previous knowledge to work through solutions. When students discover how mathematical systems work, they can solve almost anything.

I choose a variety of math problems at all levels to begin. Varying math topics and levels help students learn to be flexible in their thinking and to transfer learning from one topic to another with ease. To create excitement, I change the names of the people in the problems to the names of students in my class. This leads to wonderful interactions which, in turn, leads to sharing ideas and helping one another. Each student gets a folder of problems. I put them on label paper so they can stick them in their math journals, one problem at a time. I don’t specify in which order students should work the problems – leaving it open-ended makes the math more engaging, encouraging students to ask questions of each other.

Some students like to work alone, while others prefer to connect with partners to work on problems they have in common. Using Exemplars legitimizes working with partners. It teaches students to share strategies, talk to others, and collaborate. Traditionally, teachers have considered the sharing of math work to be “cheating,” but I have found the learning to be so much better for all when my students share solutions. Math at The Phoenix School often becomes a social event as we collaborate on a particularly complex challenge, especially when we turn to using materials to represent a solution. Everyone’s ideas are considered and sometimes debated with passion!

I discuss different approaches to solving problems with students and expect them to document their work using charts/graphs/tables, words, numbers, equations, pictures/diagrams, and personal reflection. This helps students see math in multiple ways, which increases the learning. Requiring visual representations helps students organize their thinking so that, as I say to them, “Your paper talks to me. I can tell exactly what you were thinking as you worked through the problem.” For my older students, I always use the more challenging form of each problem. It is easy to extend these problems into algebra since so many lend themselves to finding the pattern and taking it to the algebraic equation.

From our youngest students to our oldest, we find that Exemplars problems engage, challenge, and create mathematical thinkers at every level. Our math program is truly strengthened by the Exemplars component.

Understanding Mathematical Connections

Thursday, March 29th, 2018

Written By: Deborah Armitage, M.Ed., Exemplars Math Consultant

What is a mathematical connection? Why are mathematical connections important? Why are they considered part of the Exemplars rubric criteria? And how can I encourage my students to become more independent in making mathematical connections?

This blog represents Part 1 of a four-part series that explores mathematical connections and offers guidelines, strategies and suggestions for helping teachers elicit this type of thinking from their students. We find many students enjoy making connections once they learn how to reflect and question effectively.

A Brief Introduction to the Exemplars Rubric

The Exemplars assessment rubric allows teachers to examine student work against a set of analytic assessment criteria to determine where the student is performing in relationship to each of these criteria. Teachers use this tool to evaluate their students’ problem-solving abilities.

The Exemplars assessment rubric is designed to identify what is important, define what meets the standard and distinguish between different levels of student performance. The rubric consists of four performance levels — Novice, Apprentice, Practitioner (meets the standard) and Expert — and five assessment categories (Problem Solving, Reasoning and Proof, Communication, Connections and Representation). Our rubric criteria reflect the Common Core Standards for Mathematical Practice and parallel the National Council of Teachers of Mathematics (NCTM) Process Standards.

The Importance of Mathematical Connections

Exemplars refers to connections as “mathematically relevant observations that students make about their problem-solving solutions.” Connections require students to look at their solutions and reflect. What a student notices in her or his solution links to current or prior learning, helps that student discover new learning and relates the solution mathematically to one’s own world. A student is considered proficient in meeting this rubric criterion when “mathematical connections or observations are recognized that link both the mathematics and the situation in the task.”

NCTM defines mathematical connections in Principals and Standards for School Mathematics as the ability to “recognize and use connections among mathematical ideas; understand how mathematical ideas interconnect and build on one another to produce a coherent whole; recognize and apply mathematics in contexts outside of mathematics.” (64)

The Common Core State Standards for Mathematics (CCSSM) support the need for students to make mathematical connections in problem solving. Reference to this can be found in the following Standards for Mathematical Practice:

  • MP3: Construct viable arguments and critique the reasoning of others. “… They justify their conclusions, communicate them to others, and respond to the arguments of others.”
  • MP4: Model with mathematics. “… They routinely interpret their mathematical results in the context of the situation and reflect on whether the results make sense, possibly improving the model if it has not served its purpose.”
  • MP6: Attend to precision. “Mathematically proficient students try to communicate precisely to others. They try to use clear definitions in discussion with others and in their own reasoning. They state the meaning of the symbols they choose … They are careful about specifying the units of measure and labeling axes … They calculate accurately and efficiently express numerical answers with a degree of precision appropriate …”
  • MP7: Look for and make use of structure. “Mathematically proficient students look closely to discern a pattern or structure …”
  • MP8: Look for and express regularity in repeated reasoning. “… They continually evaluate the reasonableness of their intermediate results.”

The CCSSM also state, “The Standards for Mathematical Content are a balanced combination of procedure and understanding. Expectations that begin with the word ‘understand’ are often especially good opportunities to connect the practices to the content. Students who lack understanding of a topic may rely on procedures too heavily. Without a flexible base from which to work, they may be less likely to consider analogous problems, represent problems coherently, justify conclusions, apply the mathematics to practical situations …” (Common Core Standards Initiative, 2015)

When students apply the criteria of the Exemplars rubric, they understand that their solution is more than just stating an answer. Part of that solution is taking time to reflect on their work and make a mathematical connection to share.

What Can Teachers Do to Help Students Make Mathematically Relevant Connections?

When students begin to explore mathematical connections, teachers should take the lead by providing formative assessment tasks that introduce new learning opportunities and provide practice, so they may become independent problem solvers. As part of this process, teachers will want to focus on five key areas to help students develop an understanding of mathematical connections.

(1) Develop students’ abilities to use multiple strategies or representations to show their mathematical thinking and support that their answers are correct. When students demonstrate an additional or new strategy or representation in solving a problem, a mathematical connection is made. The Common Core includes a variety of representations students can apply to solve a problem and justify their thinking. Examples include manipulatives, models, five and ten frames, diagrams, keys, number lines, tally charts, tables, charts, arrays, picture graphs, bar graphs, linear graphs, graphs with coordinates, area/visual models, set models, linear models and line plots. By practicing these different approaches, students will begin to create new strategies and representations that are accurate and appropriate to their grade level. This in turn opens the door for them to use a second or even third representation to show their thinking in a new way or to justify and support that their answer(s) is correct.

Using formative problem-solving tasks to introduce and practice new strategies and representations is part of the problem-solving process. Teachers should provide formal instruction so that students may grow to independently determine and construct strategies or representations that match the task they are given. An example of this can be seen in the primary grades when many teachers introduce representations in the following order: manipulative/model, to diagram (including a key when students are ready), to five/ten frames, to tally charts, to tables, to number lines. This order allows students to move from the most concrete to the more abstract representations.

(2) Encourage students to continue their representations. Mathematical connections may be made when students continue a representation beyond the correct answer. Examples of this can be seen when a table or linear graph is continued from seven days to 14 days or when two more cats are added to a diagram of 10 cats to discover how many total ears a dozen cats would have. Another example includes adding supplemental information to a chart such as a column for decimals in a table that already has a column indicating the fractional data. In this case, the student extends his or her thinking to incorporate other mathematics to solve the task. It is important to note that connections must be relevant to the task at hand. In order to meet the standard, a connection must link the math in the task to the situation in the task.

(3) Explore the rich formal language of mathematics. Mathematical connections may be made as students begin to use the formal language of mathematics and its connection to their representations, calculations and solutions. Mathematical connections can be seen in the following examples: two books is called a pair; 12 papers is a dozen, the pattern is a multiple of 10; 13 is a prime number so 13 balls can’t be equally placed in two buckets; and the triangle formed is isosceles. The input and output on a table can also help students generalize a rule with defined variables. Students will quickly learn that making connections promotes math communication (formal terms and symbols) and that using math communication promotes connections. Again, these connections must link the math in the task to the situation that has been presented.

(4) Incorporate inquiry into the problem-solving process. Asking students to clarify, explain, support a part of their solution to a math partner, the whole class, or a teacher, not only helps develop independent problem solvers but also leads to more math connections. In your discussions, use verbs from Depth of Knowledge 2 (identify, interpret, state important information/cues, compare, relate, make an observation, show) and from Depth of Knowledge 3 (construct, formulate, verify, explain math phenomena, hypothesize, differentiate, revise). By asking students questions that provide them the opportunity to show and share what they know, connections become a natural part of their solutions.

Instead of asking, “Do you see a pattern in your table?” say, “Did you notice anything about the numbers in each column in your table?” Try asking a primary student, “I know you have a cat. Would you like your cat to join the cats in your problem?” “What new numbers are you using?” “I heard you tell Maria that all the numbers in your second column are even. Can you help me understand why they are all even numbers?” Every time a student provides you with a correct answer to your or another student’s inquiry, stop and say, “Thank you for explaining/showing/sharing your thinking. You just made a mathematical connection about your problem.” If you hear a student make a mathematical connection outside of class, stop and comment, “You just made a math connection!” Some examples of these student connections may include, “Look, we are lined up as girl, boy, girl, boy, girl, boy for lunch. That is a pattern,” “In four more days it is my birthday,” “Art class is in 15 minutes because we always go to art at 10 o’clock,” “We can have an equal number of kids at each table because four times six equals 24,” “My dad says we have to drive 45 miles per hour because that is the speed limit, so I think I can write each student as ‘per student’” or “I think I can state all the decimals on my table as fractions.”

(5) Encourage self- and peer-assessment opportunities in your classroom. Encourage students to self-assess their problem-solving solutions either independently, with a math partner or with the support of their teacher. The more opportunity students have to use the criteria of the Exemplars assessment rubric to evaluate their work, the more independent they become in forming their solutions, which will include making mathematically relevant connections.

Exploring Authentic Examples of Mathematical Connections

In the next blog post of this series, we’ll look at a problem-solving task and student solution from Grade 1 to observe how mathematical connections have been effectively incorporated. We’ll also explore the type of support a teacher may provide during this learning time as well as the type of support students may give each other. (Solutions from Grades 3 and 5 will follow in subsequent posts of this series.)

 

Plainville Community Schools and Exemplars Math

Wednesday, March 28th, 2018

Written By: Phil Sanders, Math/Science Instructional Leader

Plainville Schools has had a long-standing relationship with Exemplars. We have been using their tasks for more than ten years. It wasn’t until two years ago, however, that we really decided to put the Exemplars problem-solving methods to full use. With the Smarter Balanced Assessment, we noticed a lack of growth in our students on the Performance Task. This year, we decided to address this issue. Exemplars was a perfect fit.

Our district started by sending our Math Leadership team to an Exemplars Institute with Deb Armitage. This session gave the team a comprehensive understanding of how to incorporate Exemplars problem-solving methods successfully into the classroom. We learned that we could use the problems in several ways: Teachers could use them as instructional material for students in small groups as well as for whole-class instruction. These problems could also be used to provide formative information to guide the instruction and understanding of how to solve this type of performance task. Most of our teachers, for example, use the Exemplars tasks in the middle of a unit to provide information and then at the end as a summative assessment. The information we gather helps to differentiate our instruction and provides us with intervention grouping for both higher and lower levels of understanding. Our teachers appreciate being able to pick problems that are aligned to the Common Core Standards; students like the problems because they are challenging and allow them to showcase their mathematical thinking and understanding. After a problem has been completed, we usually have a gallery walk, where the students get the opportunity to explain their thinking and use of models.

Exemplars materials were first introduced to teachers during our August professional development. We had teachers at each grade level solve a task and create anchor sets to be used for instruction. To introduce the problems to students, we made PowerPoint slideshows for many of the tasks. These slideshows had interesting pictures, which helped build students’ level of understanding. During the school year, students regularly asked if they were going to see a slideshow for math that day! As the school year progressed, we slowly reduced the reliance on the slideshows as students gained confidence in reading and in developing their understanding of the problems.

Our goal for the past year was to increase student understanding of performance tasks. We saw excellent improvement in students’ understanding of how to break down a problem and model their thinking. I can remember many blank papers in years past when we administered problem-solving tasks. This year we had not one single blank paper! All students were able to find an entry point to begin the task.

We attribute the success to several factors. We feel that grouping students in three different ways has removed the stigma of this type of math problem. Using the small group, paired and individual methods for students to solve tasks provides multiple ways to approach students’ learning needs. We also used the Exemplars anchor papers to show students how problems can be solved in different ways. The anchor papers helped teachers gain a better understanding of the material as well. This year, we dedicated our Math PLC to Exemplars and problem solving. Teachers from each grade level across the district gathered once a month to look at student work and discuss their successes and ways to improve instruction.

We have found Exemplars to be very helpful in meeting our goals.

Exemplars in the Classroom: “They Want to Become Experts.”

Tuesday, March 27th, 2018

Written By: Danielle Descarfino, Fifth Grade Teacher at P.S. 94 in Brooklyn

Getting Started

From the beginning of the school year, I used Exemplars problem-solving tasks regularly to create routines that have helped my fifth grade students grow and succeed. Following the Problem-Solving Procedure is a central part of this.

Although each task is different, the procedure helps kids internalize a framework for approaching a problem. I provided each student with his or her own color copy (in a sheet protector for safe keeping.) Each time we begin an Exemplars task, the students take out their Problem-Solving Procedures and refer to it. I also have a poster-sized version prominently displayed in the classroom, which I hold up and point to while guiding and facilitating tasks.

Building Background Knowledge

My class is made up of English Language Learners and former English Language Learners, so I anticipate that reading and understanding the problem may be especially challenging for them. We read the problem together, I ask questions to activate their background knowledge, and I often provide pictures that help them visualize the problem.

For example, we recently completed “A New Aquarium,” a 5.MD.C.5a task involving volume. We had been working on this math concept for only a few days and this was our first volume Exemplars task. Before reading the problem, I displayed a photo of an aquarium on the Smart Board and discussed the following questions with the class:

  • What is an aquarium?
  • What type of solid is this aquarium?
  • How could you figure out how much space this aquarium takes up? What steps would you take?

Although many students initially were not familiar with the word “aquarium,” after this discussion, they understood that an aquarium is a fish tank and a rectangular prism, which meant that we would be calculating its volume to find out how much space it takes up. Using visual aids and background questions to ensure that students understand the situation in the problem has been very helpful when completing Exemplars with English Language Learners.

Differentiation

We always utilize the differentiated Exemplars tasks. Students are aware of which problem-solving group they are in and know where to sit when it is time for an Exemplars task. One group gets the More Accessible Version; they are guided through the problem as they work with the Special Education teacher at a kidney-shaped table. The other two groups receive the Grade Level and More Challenging versions and sit with their groups in desk clusters, like a team of problem solvers.

For the Grade Level and More Challenging groups, we discuss background information, read the problem out loud, annotate it, and write our “I have to find …” statements. Then the students go on to work with their groups to complete the task while the teacher takes on the role of a facilitator, conferring with groups. Students share ideas, address misconceptions, and explain their mathematical reasoning to one another as they solve.

Motivating Students

I love hanging Exemplars tasks on bulletin boards. I think it’s useful for students to look at the page and see all of the different ways their classmates organize and express their mathematical thinking through equations, representations, and writing.

From day one, I have made it clear that it is expected that their finished work clearly communicate their problem-solving steps to the reader. Not only should the students make an effort to write neatly, but they should also organize their problem-solving steps on the page in a way that makes sense. Sometimes if a student is not showing all of their steps or it is unclear, I’ll say, “I am confused. When I look at your paper, I don’t understand the steps you took to solve the problem.” When the students have the understanding that a goal is to communicate their math thinking to a reader, it helps them create a higher-quality finished product.

Another great way to motivate students is through mathematical connections. I have given a strong emphasis to connections, as I initially noticed that once students solve the problem, they feel like they are done! This is not the case, because noticing mathematical connections, patterns, and alternate strategies really helps students understand mathematics on a deeper level and practice critical thinking skills.

To help them stretch their thinking, I discourage students from writing “boring” connections, like “This number is greater than that number” or “John ate the least amount of pizza.” Instead, I encourage them to use mathematical language, create a second representation, show steps to solving with alternate strategies, convert fractions/decimals/percents, or extend the problem by adding to the story in the original problem. Once they get the hang of it, they start being more creative, going above and beyond to make more complex math connections. During the volume unit, I taught students how to use grid paper to make scaled models of rectangular prisms. When completing these tasks, many students decided to build models to represent the rectangular prisms in the task and attach them to make 3-D Exemplars. They looked great, and the students loved making them!

Peer Assessing

At the beginning of the year, I explained each portion of the Exemplars rubric to the students. The rubrics are very student-friendly and I find that they inspire students to want to become Experts.

Each time I assess Exemplars, I use the rubric along with a sticky note full of feedback. The sticky note always contains one “Glow,” something the student did well, and one “Grow,” something the student could improve upon. At the beginning of the year, I let the students know that when they become more comfortable with Exemplars, they would learn how to peer assess. After a few months, I told the students that they were ready to peer assess one another’s work. They were so excited! This made them feel proud that they had reached a new level of expertise in problem solving and feel empowered that they were now trusted to assess a classmate’s work.

To peer assess, they do exactly as the teacher has done all year: complete the student rubric and use a sticky note to write “Glow and Grow” feedback. An example of this can be seen below. From the start, I was so impressed at how well the students were able to assess one another’s work with Exemplars. I found that regularly providing students with written feedback and referring to the rubric when expressing expectations is a great way to model peer-assessment. Furthermore, the experience of assessing Exemplars helps students get new ideas from their classmates and become more aware of how their own work will be graded.

Task: A New Aquarium

(More Accessible Version)

Joseph has a new rectangular aquarium. The aquarium has a length of four feet, a width of two feet, and a height of two feet. What is the volume of Joseph’s new aquarium? An aquarium holds one inch in length of fish for each twelve square inches of the area of the base of the aquarium. Joseph can buy fish in two different sizes—about three inches in length or about five inches in length. About how many three-inch fish can Joseph put in the new aquarium? About how many five-inch fish can Joseph put in the new aquarium? Show all your mathematical thinking.

Where to Begin? Getting Started With Exemplars Science

Wednesday, September 27th, 2017

By Tracy Lavallee, 4th Grade Teacher and Exemplars Science Consultant

Exemplars Science is not a stand-alone program.

Rather it is a supplemental program to help schools and districts bring standards-aligned, inquiry and performance-based instruction and assessment into their classrooms. The tasks can be used in a multitude of ways, for both instructional and assessment purposes.

 

Tips for Getting Started With Exemplars Science

  • Begin by looking at your curriculum. What units of study are you currently teaching? What concepts and skills are you assessing? When do you assess your students’ understanding? Where might you add formative assessment? Where could you add more inquiry-rich tasks? Do you currently use a rubric for assessment?
  • Start small. Pick one task to add to your existing unit, for instruction or assessment. Try it out.
  • Work with colleagues. It is very helpful to meet with colleagues and discuss possible tasks to use for assessment. This will add consistency at grade levels and can provide opportunities for teachers to share and analyze student work together. These rich conversations can help facilitate more effective instruction and differentiation, and deepen students’ understanding of sometimes complex concepts. It is also an opportunity to help each other be the best teachers we can be for our students.

Ways to Use Exemplars Science

  • Pre-Assessment Task: Often we forget the importance of pre-assessing students to see what they already know about a particular concept. A pre-assessment is a powerful tool for teaching. It gives us a starting place. It helps us to identify any misconceptions students may have so that we can design our instruction to address those.
  • Anchor Task: An anchor task is used at the beginning of a unit to engage students with the content and the materials. It can also be used to pre-assess students’ prior knowledge and a way to elicit misconceptions students may have. But its main purpose is engagement with the phenomenon. For a unit on electrical circuits, “Can You Light the Bulb?” (a 3-5 Exemplars investigation) is a great anchor task to try. During this investigation, students use materials to explore how to light a bulb, engage with the big ideas of the unit, grapple with a problem, collaborate with others, and communicate their thinking and learning.
  • Inquiry/Content Task: Many of the Exemplars tasks may be used to enrich units of study by adding more inquiry-based learning. They are also designed to help students deepen their conceptual understanding. For example, the 3-5 investigation, “Learning About Electricity, Part 2: How Many Electrical Circuits Can You Make?” engages students with concepts of parallel and series circuits and helps them to understand and demonstrate the difference. It also provides an opportunity for students to practice inquiry skills such as observation, designing and testing ideas, gathering data and communicating explanations and solutions. Many Exemplars science tasks are effective for teaching and practicing the skills of science and engineering.
  • Formative Assessment: Formative assessments happen throughout a unit. They can be very intentional as a means to gather information about what your students know and are able to do at different points. They can also be very informal check-ins to see what instructional modifications or changes need to be made to help students with certain concepts and skills. An example of a formative assessment in a unit on electricity might include the task, “Can You Get Two Light Bulbs to Light?” In this setting, this 3-5 task may be used to check on students’ understanding of circuits and how they work. Most Exemplars tasks can be used for formative assessment purposes.
  • Cumulative Assessment: Cumulative assessments are an important part of classroom assessment. They not only ask students to demonstrate conceptual understanding but serve as real-world opportunity for them to apply that understanding. Exemplars performance tasks are designed to be real-world applications of knowledge and skills. The 3-5 investigation “Can You Wire a House?” may be used at the end of the unit to assess students’ understanding of the concepts and their ability to communicate their understanding. It also asks students to apply their understanding to solve a problem and design a possible solution.

These are just a few suggestions for getting started with Exemplars Science. There is no right or wrong way to begin. The important thing is to begin. Have fun with it! Our tasks are teacher- and student-tested and approved. We are also here to help you and your school as you implement Exemplars into your teaching and to support you as you go.
