Turnaround facts (commutative property)
The order of the factors does not change the product: 3 × 8 and 8 × 3 are both 24. Once children know this commutative property, a fact they find hard (8 × 3) can be solved with one they know (3 × 8).
How to solve this
- Multiplication is commutative: changing the order of the factors does not change the product.
- For every fact such as 3 × 7 = 21, there is a partner: 7 × 3 = 21 — write them both.
- Check by verifying that both equations give the same product and together form a commutative pair.
Examples
3 × 8 = 24
8 × 3 = 24
7 × 4 = ?
4 × 7 = 28
