### Common Core Content Standards and Evidence

#### K.OA Operations and Algebraic Thinking

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.

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

### Possible Solutions

Ryan has 5 more animal pictures to draw.

### 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.
• 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

The Southwest Vermont Supervisory Union (SVSU) in Bennington was trying to help its local community gain a better understanding of what students need to demonstrate in order to be successful on their math assessments. One of the most difficult sections of the exam is problem solving. Here, students are not only expected to determine the correct strategy, but also to explain their answers in writing, using math language and representation. For four years SVSU has used Exemplars as a curriculum tool in teaching its students how to solve these types of problems...
