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
