Division Strategies
Division as Repeated Subtraction
42 divided by 7 Repeatedly subtract 7 from 42 until you reach a difference of 0
42-7= 35
35-7=28
28-7=21
21-7=14
14-7=7
7-7=0
Now count how many times you subtracted 7
You subtracted 6 times, so the quotient (answer to a division equation) is 6.
More Repeated Subtraction, using powerful facts
36 divided by 2
Think powerful! If I know 2 x 1 then I know 2 x 10
So instead of subtracting 2 repeatedly, I can start by subtracting 20
36-20 = 16 (since I subtracted 20, that's the same as 10 two's)
Now think 2 x ?? = 16........ 8!
Subtract 16
16-16 = 0 (Since I subtracted 16, that's the same as 8 two's)
So how many times did I subtract 2? Well, 10 + 8 = 18
So, 36 divided by 2 = 18
