Purpose

The purpose of this activity is to help students learn groupings within 10. For example 3 and 7 make 10; 8 and 2 make 10.

Achievement Objectives

NA1-3: Know groupings with five, within ten, and with ten.

Specific Learning Outcomes

Recall groupings within 10, for example 3 and 7 make 10; 8 and 2 make 10.

Activity

- Tell the students they are going to be working with strings of numbers and finding two numbers that add up to 10.
- Write three numbers on the board, ensuring that two of the numbers add to ten. For example: 7,4,3
- Ask:
*Which two numbers add together to make 10?* - Once the students have identified the correct number pair, reinforce the number fact:
*That’s right, 7 and 3 make 10.* - Repeat with several different strings of numbers.
- Have students work with a partner. Each student writes three numbers, two of which add to 10. Students then swap their work and find the pair of numbers that adds to 10 in their partners work.
