2 × 4 and 4 × 2 are 8. 8 ÷ 2 = 4 and 8 ÷ 4 = 2. Can you see how 2, 4, and 8
are related? That’s why they’re called a fact family. Each of the triangles below
shows a fact family. Write 2 multiplication and 2 division facts for each family.
The first one has been done for you.

Nine of the fact families whose members are all less than 100 have “twins” or
two family members that are the same number. One of these families is 6 × 6 =
36 and 36 ÷ 6 = 6 Another is 3 × 3 = 9 and 9 ÷ 3 = 3 List the other fact families whose members are less than 100 that have twins. One of these families has
triplets–which one?
