The pattern behind the list
Look at the last digit of each answer. From 4 × 1 to 4 × 10 it goes like this, and then the same pattern repeats every ten facts all the way up to 4 × 30:
- 4
- 8
- 2
- 6
- 0
- 4
- 8
- 2
- 6
- 0
Working out big facts
You do not need to learn all 30 facts by heart. Use the method for the 4 times table instead: Times 4 means doubling twice: double the number, then double the answer.
Double 30 to get 60, then double again to get 120.
4 × 30 = 2 × 60 = 120
