**A strategy for multiplying**

2
Multiplying using the Grid Method

3
**Partition each number first**

24 x 35= X 20 4 30 5

4
24 x 35= X 20 4 30 5

5
24 x 35= X 20 4 30 5 100

6
24 x 35= X 20 4 30 600 5 100

7
24 x 35= X 20 4 30 600 120 5 100

8
24 x 35= X 20 4 30 600 120 5 100 25 7 2 + 1 5

9
24 x 35= X 20 4 30 600 120 5 100 25 7 2 + 1 5 5

10
24 x 35= X 20 4 30 600 120 5 100 25 7 2 + 1 5 4 5

11
24 x 35= X 20 4 30 600 120 5 100 25 7 2 + 1 5 8 4 5

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

13
A strategy for dividing…

14
…using the ‘chunking’ method

15
84 ÷ 6 = 14 14 6 84 we know 10 x 24 we know 4 x

16
192 ÷ 8 = 24 24 8 192 we know 10 x 112 we know 10 x 32 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. Each lesson – a LO / a focus

**Jack had £1000 to go on holiday**

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 50 5 10 4 500 50 200 20+ 770 500 50 55 x 14 = 200 20 +30 +200 = 770 800 1000

22
230 ÷ 5 = 46 46 5 230 we know 10 x 180 we know 30 x 30 we know 6 x

23
Check : £46 x £5 = £230 ???
