What this lesson shows
7 apples, and 2 are eaten. Cross out 2, and 5 are left: 7 − 2 = 5.
The worked example
The lesson works this one step by step: 7 − 2. Then your kid tries one like it on paper.
The steps
- Start with them all
- Cross out the ones taken
- Count the ones left
- Write it with numbers
Helping at home
Read each box aloud. Your kid crosses out the ones taken away, counts the ones left, and writes the number. Say it both ways: "7 take away 2 is 5" and "7 minus 2 equals 5".
If your kid gets stuck
Cross out the ones taken away. Count the rest.
