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

2 groups of or 2 lots of

Double the number

Skip count in 2s

Add the number to itself e.g. 2x6=6+6=12

Learn your 2 times tables

**Divide Ã· / by two:**

How many times does 2 go into

Break into 2 groups

Half of

Skip count in 2s and count the 2s

Keep subtracting 2 from the number e.g. 6-2-2-2=0 so 2 goes into 6 exactly 3 times

Reverse your 2 times tables 3x2=6 so 6Ã·2=3 and 6Ã·3=2

**Add + two:**

Count two on from the original number

Learn addition rules e.g. 7+2=9 so 67+2=69

**Take - two:**

Count two back from the original number

Learn subtraction rules e.g. 7-2=5 so 67-2=65
