Times Tables to 12

By Year 4, you should be working towards knowing all your times tables up to 12 × 12. Here are some of the trickier ones to remember:

× 7 Facts

7 × 6 = 42

7 × 7 = 49

7 × 8 = 56

7 × 9 = 63

7 × 12 = 84

× 8 Facts

8 × 6 = 48

8 × 7 = 56

8 × 8 = 64

8 × 9 = 72

8 × 12 = 96

× 12 Facts

12 × 6 = 72

12 × 7 = 84

12 × 8 = 96

12 × 9 = 108

12 × 12 = 144

💡 Handy Tricks

  • ● × 9 trick: Multiply by 10, then subtract the number. E.g. 7 × 9 = 70 − 7 = 63
  • ● × 12 trick: Multiply by 10, then add double the number. E.g. 6 × 12 = 60 + 12 = 72
  • ● Order doesn't matter: 8 × 7 = 7 × 8 = 56

Multiplication Strategies

Partitioning (Split Strategy)

Break a number into parts, multiply each, then add:

23 × 4

= (20 × 4) + (3 × 4)

= 80 + 12

= 92

Doubling Strategy

Use doubling for × 4 and × 8:

15 × 4

Double 15 = 30 (that is × 2)

Double 30 = 60 (that is × 4)

= 60

Introduction to Long Multiplication

For bigger numbers, we can set out our work neatly using long multiplication. Let's try 34 × 6:

  3 4

×  6

Step 1: 6 × 4 = 24 (write 4, carry 2)

Step 2: 6 × 3 = 18, + 2 = 20

2 0 4

✔ Steps for Long Multiplication

  1. Write the numbers one above the other, lining up the ones column
  2. Multiply the ones digit first
  3. If the answer is 10 or more, carry the tens digit
  4. Multiply the tens digit and add any carry

Division Using Multiplication Facts

Remember: if you know your times tables, you can solve division problems!

If 9 × 8 = 72

then 72 ÷ 9 = 8

and 72 ÷ 8 = 9

If 12 × 7 = 84

then 84 ÷ 12 = 7

and 84 ÷ 7 = 12
