Key idea
![Page 17: Time to Teach Presents Year 5 (National Numeracy Strategy) (Based on DFEE Sample Lessons) .](https://reader036.fdocuments.net/reader036/viewer/2022062422/56649f275503460f94c3fe9a/html5/thumbnails/17.jpg)
Main Learning Task
• Today the class will do work on developing their written methods of division.
![Page 18: Time to Teach Presents Year 5 (National Numeracy Strategy) (Based on DFEE Sample Lessons) .](https://reader036.fdocuments.net/reader036/viewer/2022062422/56649f275503460f94c3fe9a/html5/thumbnails/18.jpg)
Main Learning Task
• There are two main types of division:
• Sharing and grouping.
• First we are going to use the whole class and share you out equally into four teams…
![Page 19: Time to Teach Presents Year 5 (National Numeracy Strategy) (Based on DFEE Sample Lessons) .](https://reader036.fdocuments.net/reader036/viewer/2022062422/56649f275503460f94c3fe9a/html5/thumbnails/19.jpg)
Main Learning Task• Get into four teams.
• Write what has happened on the board.
• Everyone return to your seat.
• Then write down the number calculation using conventional symbols.
![Page 20: Time to Teach Presents Year 5 (National Numeracy Strategy) (Based on DFEE Sample Lessons) .](https://reader036.fdocuments.net/reader036/viewer/2022062422/56649f275503460f94c3fe9a/html5/thumbnails/20.jpg)
Main Learning Task• Now divide the class into
groups of four.
• Write down what happened on the board.
• Everyone return to your seats.
• Write the number calculation using conventional symbols.
![Page 21: Time to Teach Presents Year 5 (National Numeracy Strategy) (Based on DFEE Sample Lessons) .](https://reader036.fdocuments.net/reader036/viewer/2022062422/56649f275503460f94c3fe9a/html5/thumbnails/21.jpg)
Main Learning Task• There are two ways of dividing a
number.
• We shared children between four teams.
• We grouped children into fours.
![Page 22: Time to Teach Presents Year 5 (National Numeracy Strategy) (Based on DFEE Sample Lessons) .](https://reader036.fdocuments.net/reader036/viewer/2022062422/56649f275503460f94c3fe9a/html5/thumbnails/22.jpg)
Main Learning Task
• When we went into teams, we knew how many teams there were, but did not know how many in each team.
• In the second case we knew how many were in each group, but not how many groups we would have.
![Page 23: Time to Teach Presents Year 5 (National Numeracy Strategy) (Based on DFEE Sample Lessons) .](https://reader036.fdocuments.net/reader036/viewer/2022062422/56649f275503460f94c3fe9a/html5/thumbnails/23.jpg)
Main Learning Task• Lets now try to solve this problem.
380 apples must be packed equally into 9 boxes.
How many apples will be in each box?
Is this a sharing or a grouping problem?
![Page 24: Time to Teach Presents Year 5 (National Numeracy Strategy) (Based on DFEE Sample Lessons) .](https://reader036.fdocuments.net/reader036/viewer/2022062422/56649f275503460f94c3fe9a/html5/thumbnails/24.jpg)
Main Learning Task• We shall start with the repeated subtraction
380 apples must be packed equally into 9 boxes.
How many apples will be in each box?
380 apples in 9 boxes
380 -180 (20 apples in each
box) 200 -180 (20 apples in each
box) 20 -18 (2 apples in each
box) 242 apples in each box and
2 apples left over.
![Page 25: Time to Teach Presents Year 5 (National Numeracy Strategy) (Based on DFEE Sample Lessons) .](https://reader036.fdocuments.net/reader036/viewer/2022062422/56649f275503460f94c3fe9a/html5/thumbnails/25.jpg)
Main Learning Task• Compare this way to a more efficient way.
380 apples in 9 boxes
380 -180 (20 apples in each
box) 200 -180 (20 apples in each
box) 20 -18 (2 apples in each
box) 242 apples in each box and
2 apples left over.
9 360 - 360 40 x 9 20 - 18 2 x
9 2Answer42 Apples and 2
apples left over.

Main Learning Task
• Get into pairs.
• You now must solve this problem on your own.

Plenary
• Sit with your partner.
• Make up a real life division problem using a different context and describe whether it is a sharing or a grouping problem.
• Draw a picture to help you decide.
![Page 30: Time to Teach Presents Year 5 (National Numeracy Strategy) (Based on DFEE Sample Lessons) .](https://reader036.fdocuments.net/reader036/viewer/2022062422/56649f275503460f94c3fe9a/html5/thumbnails/30.jpg)
Plenary• The pair presents the problem
to the class.
• Discuss which kind of problem it is.
• For homework – solve your problem attempting to use the written method.
