Understanding 2

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 ÷ / 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 6÷2=3 and 6÷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
