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

3 groups of or 3 lots of

Triple the number

Skip count in 3s

Add the number to itself and then again 3x6=6+6+6=18

Learn your 3 times tables

**Divide ÷ / by three:**

How many times does 3 go into

Break into 3 groups

One third of

Skip count in 3s and count how many 3s

Keep subtracting 3 from the number e.g. 9-3-3-3=0 so 3 goes into 9 exactly 3 times

Reverse your 3 times tables 3x2=6 so 6÷2=3 and 6÷3=2

**Add + three:**

Count three on from the original number

Learn addition rules e.g. 6+3=9 so 66+3=69

**Take - three:**

Count two back from the original number

Learn subtraction rules e.g. 7-3=4 so 67-3=64
