Lesson overview

Number - multiplication and division

Knowing a multiplication table fact helps us with related facts. If 4 x 6 = 24, then 24 ÷ 4 = 6 and 24 ÷ 6 = 4. The 8 times table can also be built from doubling the 4 times table.

Three times table

3 x 4 = 12 means 3 groups of 4 make 12.

The matching division fact is 12 ÷ 3 = 4.

Four times table

4 x 5 = 20 and 20 ÷ 5 = 4 belong to the same fact family.

Multiplication and division facts are linked.

Eight times table

8 x 3 = 24. This is double 4 x 3.

The 8 times table can be built from doubles.

Worked example

Use 4 x 7 = 28 to write two division facts.

Multiplication4 x 7 = 28
Division28 ÷ 4 = 7
Division28 ÷ 7 = 4
  1. Start with the known multiplication fact.
  2. Use the product 28 as the starting number for division.
  3. 28 divided by 4 gives 7.
  4. 28 divided by 7 gives 4.

Try it

Use the multiplication fact you know, then think about the matching division facts.

Common mistakes

Watch for these when working through the lesson.

  • Swapping the product with one of the factors.
  • Forgetting that the division fact must use the total.
  • Mixing a 4 times fact with an 8 times fact.
