**Multiply x * . () by four:**

4 groups of or 4 lots of

Quadruple the number

Skip count in 4s

Double the number then double again

Learn your 4 times tables

**Divide ÷ / by four:**

How many times does 4 go into

Break into 4 groups

One quarter of

Skip count in 4s and count the 4s

Keep subtracting 4 from the number 12-4-4-4=0 so 4 goes into 12 exactly 3 times

Reverse your 4 times tables 3x4=12 so 12÷4=3 and 12÷3=4

**Add + four:**

Count 4 on from the original number

Learn addition rules e.g. 5+4=9 so 65+4=69

**Take - four:**

Count 4 back from the original number

Learn subtraction rules e.g. 7-4=3 so 67-4=63
