1 Division methods Splitting/ using factors Repeated subtraction Guessing, then multiplying to check Traditional

2 Splitting/ using factors e.g.,208  4 4=2x2, So, divide by 2 twice 208  2 =104 104  2 =52

3 Splitting/ using factors e.g.,126  9 9=3x3, So, divide by 3 twice 126  3 =42 42  3 =14

4 Repeated subtraction e.g., 72  9 1.72-9 =63 2.63-9 =54 3.54-9 =45 4.45-9 =36 5.36-9 =27 6.27-9 =18 7.18-9 =9 8.9-9 =0 72  9 =8 Because 9 was subtracted 8 times

5 Repeated subtraction e.g., 491  31 1.491-310 =181 2.181-31=150 3.150-31=119 4.119-31=88 5.88-31=57 6.57-31=26 31x10 and 31x5 were subtracted So, 491  31=15 r26

6 Guess, then multiply 234  9 Guess: 25 25 X 9 225 This is 9 less than 234 Therefore, 234  9 = 26

8 Traditional 491  31 31 4 9 1 1 155 1 5 31 18 26 491  31 = 15 r26

9 Who will get more? 6 people share 2 pizzas 12 people share 3 pizzas

10 __ 2 pizzas, 6 people 2  6= 2 __ 6 = 1 3

11 3 pizzas, 12 people __ 3  12= 3 = 1 4

12 Who will get what? 1 3 1 4 __
