What this lesson shows
Is 36 a multiple of 8? 8 × 4 = 32, 8 × 5 = 40: no.
The worked example
The lesson works this one step by step: 36 ÷ 8. Then your kid tries one like it on paper.
The steps
- Count by the number
- Lands on it: a multiple
- Jumps over: not a multiple
Helping at home
Count by the one-digit number until you reach or pass the big one. If the count lands on it, it is a multiple; if it jumps over, it is not. Say the multiplication that lands on it.
If your kid gets stuck
Count by the small number.
