Times Tables

In Year 3 you should learn the 11 times tables, 9 times tables, 3 times tables, 4 times tables.x11 x9 x3 x4

Using a multiplication square

A multiplication square is a grid that helps you quickly look up answers to times table sums.

To find the answer to 6 x 4

  1. Find 6 along the top row.
  2. Find 4 down the left column.
  3. Follow the line down and across until the two numbers meet.
  4. The square where they meet gives you the answer: 24

Multiplication and division facts

Multiplication is the reverse of division. This means you can rearrange the numbers from a multiplication sum to make a division sum.
Multiplication facts explained

Using facts you already know

You can use times table facts you already know to help you work out harder sums.

If you know that 4 x 5 = 20

Then 4 x 6 is 4 more = 24

If you know that 2 x 4 = 8

Then 4 x 4 is double 8 = 16

If you know that 10 x 3 = 30

Then 9 x 3 is 3 less = 27

Multiplying by tens, hundreds and thousands

To times by ten you add a '0' from the 10 to the number your are multiplying it by to get the answer.

5 x 10 = 50

To times by one hundred you add two '0' from the 100 to the number you are multiplying it by to get the answer.

3 x 100 = 300

To times by one thousand you add three '0' from the 1000 to the number you are multiplying it by to get the answer.

6 x 1000 = 6000

You can now work out any sum which is multiplied by 10, 100 or 1000.

56 x 100 = 5600

Here you just at two '0' from the 100 to 56 to get the correct answer.

Multiplying by the grid method

When numbers get too big to count on your fingers, you can split them up. The grid method breaks larger numbers into tens and units so that they are easier to multiply.

Work out: 42 x 5

1) Break up the 42 and add it to the grid. Put the 5 on the side.

2) Work out the sums 40 x 5 and 2 x 5. Then add the answers together.

Multiplying using a grid with 2 digits
Work out the multiplication sums by using a grid and 2 digit numbers.

If you have even bigger numbers split them in the same way to out the answer.
Work out: 52 x 13

1) Break up the 52 and add it to the top. Break up the 13 and add it to the side.

2) Work out the sums 50 x 10, 2 x 10, 50 x 3, 2 x 3.
