Kindergarten math · Unit 5: Adding and subtracting within 10

"More" does not always mean add

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

  1. Who has more?
  2. Who has fewer?
  3. Box the extra
  4. 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.
