Teaching Factors and Multiples

What it is

Factor pairs, multiples, and telling a prime number from a composite one. A factor divides the number exactly; a multiple is what you get by counting in it.

When a child is ready

Use it once the times tables are known to twelve.

If they struggle

Hunt factor pairs in order, one and the number, then two, then three, and stop when the pairs start repeating. A number with no pair except one and itself is prime.
