A strategy for multiplying

2
Multiplying using the Grid Method

3
Partition each number first 24 x 35= X

4
24 x 35= X

5
24 x 35= X

6
24 x 35= X

7
24 x 35= X

8
24 x 35= X

9
24 x 35= X

10
24 x 35= X

11
24 x 35= X

12
27 x 4 = ? 36 x 3 = ? X = 108 X = 108

13
A strategy for dividing…

14
…using the ‘chunking’ method

15
84 ÷ 6 = 684 we know 10 x we know 4 x

16
192 ÷ 8 = 1928 we know 10 x we know 10 x we know 4 x

17
How can we apply our skills

18
L.O. To identify and use appropriate operations to solve word problems. Success Criteria I understand the different vocabulary for multiplication and division. I can use RUCSAC to complete one step word problems. I can decide whether to use a mental or written method to find the answer. I can use a written method for calculations. All Blue plus: I can use RUCSAC to solve two step word problems. All Blue plus: I can use RUCSAC to solve complex multi-step word problems. I can check my answers using the inverse operation.

Jack had £1000 to go on holiday. His hotel cost £55 a night all inclusive. He stayed for 2 weeks and had a great time. On his return he shared out the money he had left with his 5 children. How much money did they each receive?

21
X X x 14 = =

22
230 ÷ 5 = 2305 we know 10 x we know 30 x we know 6 x

23
Check : £46 x £5 = £230 ???

24
