About this lesson
Repeated addition links multiplying to adding: 3 × 4 is 4 + 4 + 4. Your child adds one group at a time and skip counts to keep track: 4, 8, 12. Seeing the groups (or the rows of an array) build up shows why the total is the same however the sum is written.
What your child learns
- Count equal groups by skip counting in 2s, 5s and 10s.
