Revise Chunking

11. 78 children will be placed in teams of 6.
PROBLEM!
78 children will be placed in teams of 6.
How many teams will there be?
Q. What calculation do we need to solve this problem?
When you have decided how to do it work out the answer.

12. We need to do the division sum 78 ÷ 6. 78 - 60 ( 10 x 6 ) 18
We can do this by chunking… 78
( 10 x 6 ) 18
( 3 x 6 )
Q. How many 6’s have been subtracted?
78 ÷ 6 = 13

13. Q. What would be the answer if there had been 80 children?

14. Using pencil and paper we write… 80 ÷ 6 = 13 remainder 2
Using chunking…. 80
(10 x 6 ) 20
( 3 x 6 )
r.2
Using pencil and paper we write…
80 ÷ 6 = 13 remainder 2

15. There are 85 sweets to be shared equally among 7 children.
Try this one with a partner
There are 85 sweets to be shared equally among 7 children.
How many sweets does each child have? How many are left?

16. Using chunking… 85
-70 (10 x 7) 15
- 14 ( 2 x 7)
r.1
Using pencil and paper…
85 ÷ 7 = 12 r.1

17. In pairs discuss how you could calculate an answer to this.
175 ÷ 7
In pairs discuss how you could calculate an answer to this.

18. Using chunking…
175
- 70 (10 x 7)
105
(10 x 7) 35
- 35 ( 5 x 7)
Answer = 25

19. Try these:
134 ÷ 5
157 ÷ 6
119 ÷ 5

20. What is a quick way to check whether the answer to a division
is correct?

21. division is correct we can use the
To check whether the answer to a
division is correct we can use the
INVERSE
operation.

22. LOOK…
57 ÷ 3 = 19
Q. Which two numbers should we
multiply to check whether this
is correct?

23. 57 ÷ 3 = 19 To use the inverse operation we should multiply 19 by 3.
19 x 3 = 57

25. WALT:
Express a quotient as a fraction, or as a decimal rounded to one decimal place.

26. Mentally divide the following …
35 ÷ 5
27 ÷ 3
56 ÷ 8
49 ÷ 7
63 ÷ 9
42 ÷ 6

27. The purpose of the lesson is to consider divisions that do not always have whole number answers.

28. 46/7=
Look at this as a multiplication!
How many sevens make 46?

33. YOUR TASK! Find the closest multiple below the number.
How many 7s make this multiple?
Calculate how many sevenths to get from the closest multiple to your number.
