What this lesson shows
Fixes a mistake
Steve has 7 crayons, 3 more than Joane. So Joane has fewer: 7 take away 3 is 4.
The worked example
The lesson works this one step by step: 7 − 3. Then your kid tries one like it on paper.
The steps
- Who has more?
- Who has fewer?
- Box the extra
- Count the rest
Helping at home
Read each story aloud, twice. Ask "who has more? who has fewer?" before any numbers. Your kid boxes the extra crayons and counts the rest.
If your kid gets stuck
Who has fewer? Box the extra ones and count the rest.
