L.O.1 To be able to derive quickly division facts corresponding to tables up to 10x10
We are going to count on and back using different multiples
L.O.2 To be able to use informal pencil and paper methods to divide TU by U and HTU by U.
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.
We need to do the division sum 78 ÷ 6. We can do this by chunking… ( 10 x 6 ) ( 3 x 6 ) 0 Q. How many 6s have been subtracted? 78 ÷ 6 = 13
Q. What would be the answer if there had been 80 children?
Using chunking… (10 x 6 ) ( 3 x 6 ) 213 r.2 Using pencil and paper we write… 80 ÷ 6 = 13 remainder 2
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?
Using chunking… (10 x 7) ( 2 x 7) 112 r.1 Using pencil and paper… 85 ÷ 7 = 12 r.1
175 ÷ 7 In pairs discuss how you could calculate an answer to this.
Using chunking… (10 x 7) (10 x 7) ( 5 x 7) 0 Answer = 25
In pairs discuss how you could calculate an answer to this: 148 ÷ 6
Using chunking… ( 10 x 6) ( 10 x 6) ( 4 x 6) 4 Answer = 24 r.4
Try these: 134 ÷ ÷ ÷ 5
134 ÷ (10 x 5) (10 x 5) ( 6 x 5) 4 Answer = 26 r.4
157 ÷ (10 x 6) (10 x 6) ( 6 x 6) 1 Answer = 26 r.1
119 ÷ (10 x 5) (10 x 5) ( 3 x 5) 4 Answer = 23 r.4
Q. What is a quick way to check whether the answer to a division is correct?
To check whether the answer to a division is correct we can use the INVERSE operation.
LOOK… 57 ÷ 3 = 19 Q. Which two numbers should we multiply to check whether this is correct?
57 ÷ 3 = 19 To use the inverse operation we should multiply 19 by x 3 = 57
LOOK… 175 ÷ 7 = 25 The inverse operation shows us 25 x 7 = 175
By the end of this lesson the children should be able to: Use multiples of the divisor for TU ÷ U and HTU ÷ U calculations; Check with the inverse operation.
Lob: I can use pencil and paper methods to divide TU by U and HTU by U.
