Commutative tasks (swap)
Commutative tasks (swap) helps children practise using the rule that the order of factors does not change the product — 3 × 8 = 8 × 3 = 24. Read the short guide and look through the examples before choosing online practice or a printable worksheet.
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

Multiplication and division worksheets that follow what the child has already solved.
The app does not generate PDF sheets at random. It uses the child’s previous results, including offline sheets, so the next practice can focus on what still needs work.
- Generate printable PDFs from the child’s history.
- Enter solved offline sheets quickly after practice.
- The app shows each answer; you mark it correct or not.
