In this activity, we will be multiplying numbers by 4.
Here is the 4 times table.
Try to learn it by heart.
0 × 4 = 0
1 × 4 = 4
2 × 4 = 8
3 × 4 = 12
4 × 4 = 16
5 × 4 = 20
6 × 4 = 24
7 × 4 = 28
8 × 4 = 32
9 × 4 = 36
10 × 4 = 40
11 × 4 = 44
12 × 4 = 48
To multiply by 4, skip counting is a good technique.
4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48
If you are stuck, choose a fact you know well to count on or back from.
So, we know that 10 × 4 = 40
Count back 4 to find 9 × 4
40, 39, 38, 37, 36
Count on 4 to find 11 × 4
40, 41, 42, 43, 44
Let's look at an example
Example
Find 5 × 4.
Answer
To find 5 lots of 4, we can skip count and choose the 5th multiple.
4, 8, 12, 16, 20
5 × 4 = 20
Now you're ready to try some questions. Good luck!
