In this activity, we will be multiplying numbers by 8.
Here is the 8 times table.
Try to learn it by heart.
0 × 8 = 0
1 × 8 = 8
2 × 8 = 16
3 × 8 = 24
4 × 8 = 32
5 × 8 = 40
6 × 8 = 48
7 × 8 = 56
8 × 8 = 64
9 × 8 = 72
10 × 8 = 80
11 × 8 = 88
12 × 8 = 96
Numbers in the 8 times table end in 8, 6, 4, 2, or 0.
If you look at the facts above, you will spot that these numbers repeat in the one's place of each multiple:
8, 16, 24, 32, 40, 48, 56, 64, 72, 80, 88, 96
A tip for multiplying by eight is to double the number, then double the result and then double once more!
Let's look at an example
Example
Find 4 × 8.
Answer
We can double 4, then double the result, then double the next result too.
Double 4
4 × 2 = 8
Double 8
8 × 2 = 16
Double 16
16 × 2 = 31
4 × 8 = 32
