Today's Lesson
What to Get Ready
The following lessons are based on British currency. You may wish to teach your student about your local currency alongside these lessons. Please note, however, that the assignments will assess their understanding of money using British pence (p).
If you do not have access to British coins, print out the 📄 British Coins document which you can find in the General Resources. You can then cut out pictures of the coins you need.
Gather nine items to buy and sell at a ‘shop’, for example, familiar stationery items, small toys, and so on.
Make some simple labels for your items, from card or paper, by writing an amount onto each label, and fixing it to the item.
Amounts needed: 10p, 5p, 11p, 15p, 7p, 6p, 4p, 9p and 13p.
You could even just lay the item on top of the label, so that the price can still be seen.
Introduction
Show your student the items from the ‘shop’ with their prices attached.
Tell your student that they can spend 20p.
Encourage them to say which things are cheap and which are expensive.
Ask, ‘If you buy the 10p item, how much more can you spend?’
Ask them to spot two items that cost 10p together, or two with a total of 20p.
Ask, ‘If you decide to buy two things but not to spend all of your 20p, which pair of items can you buy?’
Choose two items and show your student how to add these by counting on from the larger number or by using a number fact you know.
Say, ‘We use counting on to add amounts to find an unknown total. For example, when we were finding out how much it would cost to buy these two items. When we count on, we don’t know where we’ll finish.’
Ask, ‘How do we find out how much money we have left?’
Demonstrate, counting up to 20.
For example, if the total of their items was 18p, you could count up from 18p to 20p to find out how much change we have left: 2p.
Say, ‘We use counting up to find the difference between two known amounts. When we count up, we do know where we’ll finish.’
Discuss how we can use pairs to 20 to help. For example, if we spend 17p, we would get 3p change because 17 + 3 = 20.
Show 17 beads and the next 3 beads to make 20 on a 1-100 bead string.
Record: 20p – 17p = 3p change.
Repeat with other teens prices.
This video demonstrates using a 0-20 number line to find change by counting up.
Main Activity
Access the 📄 Shop and Find change sheet and ask your student to choose two items with a total of less than 20p. They should then find the total, then find the change from 20p.
They should record their number sentences.
Repeat this process, until they are working confidently and independently.
Extra Challenge
Your student should choose three items totalling less than 20p and find the change.
