Summative Assessment: Grade K

Drawing Animal Pictures


Ryan is drawing ten pictures of animals to put on his bedroom door. Ryan has finished drawing five animal pictures. How many more animal pictures does Ryan have to draw? Show and tell how you know.

Common Core Content Standards and Evidence


K.OA Operations and Algebraic Thinking

Understand addition, and understand subtraction.

4.  For any number from 1 to 9, find the number that makes 10 when added to the given number, e.g., by using objects or drawings, and record the answer with a drawing or equation.

Exemplars Task-Specific Evidence

This task requires students to find the number that makes 10 when added to five.

Common Core Standards of Mathematical Practice

MP.1 Make sense of problems and persevere in solving them.
MP.3 Construct viable arguments and critique the reasoning of others.
MP.4 Model with mathematics.
MP.5 Use appropriate tools strategically.
MP.6 Attend to precision.

Possible Connections

Below are some examples of mathematical connections. Your students may discover some that are not on this list.

  • Ryan was half way done with his pictures.
  • 10 pictures is an even number.
  • 5 pictures is an odd number.
  • Relate to a similar task and state a math link.
  • Solve more than one way to verify the answer.
  • 5 made, 5 to make is a fair share of pictures.
  • There are an equal number of pictures made and pictures left to make.
  • Equations: 5 + ? = 10 and 10 – 5 = 5.
  • Double 5 is 10.
  • Half of 10 is 5.

Here's What People Are Saying

If you are a student at our school, you will have heard the term, Exemplars. Exemplars are extended tasks in which 6th graders work in cooperative groups to plan strategies and find solutions. Initially, students are presented with a particular mathematical situation and asked to brainstorm individual strategies for 'attacking' such a problem.
