Maths Year 1 Summer Money

Each unit has everything you need to teach a set of related skills and concepts. 'Teaching for Understanding' provides whole-class teaching and fully differentiated adult-led group activities. ‘Problem-solving and Reasoning’ develops these skills, and includes questions to enable you to assess mastery. Practice sheets ensure procedural fluency. Extra support activities enable targeted work with children who are well below ARE.

‘UNIT PLAN’ gives you a text version of all parts of the unit to use in your school planning documentation. ‘DOWNLOAD ALL FILES’ gives you that unit plan plus all of associated documents. These bulk downloads are added value for Hamilton Friends and School Subscribers.

National Curriculum
Meas (iii)
Add/Sub (i) (ii) (iii) (iv)

Hamilton Objectives
22. Recognise and know the value of different denominations of coins and notes.
7. Know number bonds to 10, e.g. 5 + 5, 6 + 4, etc.
8. Begin to know pairs which make 5, 6, 7, 8, 9 and 20.

12. Solve missing number problems and addition/subtraction problems in number stories.

Teaching and Group Activities for Understanding

Day 1 Teaching
Show an enlarged 0–20p number line. Mark 20p and stick 12 pennies with sticky tack under it. How many more pennies do I have to find to make 20p? Use number bonds to 10 (2 + 8) to work this out. Relate this to bonds to 20. Repeat for 15p + 5p = 20p.
Group Activities
-- Pick a money card and find the complement to 20p.
-- Listen to coins dropping into a tin; work out the complement to 20p.

Day 2 Teaching
Show pictures of differently priced toys. Children work in pairs to pick two and add the prices. Discuss which number facts they need to use. Rehearse adding pairs of toys using facts, e.g. doubles or bonds to 10 or 20: 6p + 6p and 14p + 6p.
Group Activities
Use the in-depth problem-solving investigation ‘Dicey coins’ as today’s group activity.
Or, use this activity:
-- Pretend-shopping: add two or three amounts, identifying helpful number facts where possible.

Day 3 Teaching
Display a 0–£1 penny line (see resources). What is 60p add 10p? Do we need to count on in ones? (No) Draw a jump labelled + 10p from 60p to 70p. Relate this to ‘Spider counting’ on the 100-square. Point to 70p and repeat. Write 70p + 10p = 80p. Continue like this, adding 10p and 20p to different amounts, e.g. 42p, 71p, 13p. Use the money line to show children that 100p = £1.
Group Activities
-- Calculate price increases of 10p or 20p using penny lines.
-- Calculate price increases of 10p, 20p or 30p using penny lines.

Teaching and Group Activities for Understanding

Day 1 Teaching
Display items costing under 20p and a 0–20p penny line (see resources). Choose the sweet costing 17p; mark the amount on the line. I’m going to buy this sweet – it costs 17p. I’m going to pay with this 20p coin. That’s too much money, so the shopkeeper will need to give me some money back – some change. Let’s find out how much change I should get... Demonstrate how to count up from 17p to find the change from 20p. Repeat with other items.
Group Activities
-- Role-play shops and finding the change.
-- Solve problems using the amount paid and the change given to find the cost of an item.

Day 2 Teaching
Show children a 0–20p penny line and say you have bought a rubber for 7p. Use Interactive Whiteboard coins or large mock coins to show this. Now buy a pen for 16p. How much more expensive is 16p than 7p? What is the difference between 16p and 7p? Show how to count up from 7p to 16p. Repeat for 8p and 13p.
Group Activities
Use the in-depth problem-solving investigation ‘The Puzzling Sweet Shop’ from NRICH as today’s group activity.
Or, use this activity:
-- Find the difference in price between stationery items.

Day 2
Pick two items of stationery; find the difference in price between them.

Mastery: Reasoning and Problem-Solving

  • Write the change from 20p when buying:
    (i) 16p biscuit
    (ii) 14p cracker
    (iii) 9p drink
  • True or false?
    You always get change if you pay for something with a 20p coin.
    You can buy two 8p sweets and still have change from 20p
    You pay with 20p and you spend 9p. You get more than 9p change.
  • Sam says that the difference between 13p and 6p is the same as the difference between 20p and 13p. Is he right?

Teaching and Group Activities for Understanding

Day 1 Teaching
Find totals of money using real coins (10p, 2p, and 5p). Model adding amounts in different orders, i.e. We know that 5 + 2 is 7… What is 7 add 10? We don’t need to count on in ones - we can use Spider to add 10, making 17.
Or Let’s start with the larger number…What is 10p + 5p? We can use place value to recombine these amounts… Then count on another 2p from 15p. Tap the 2p twice saying sixteen, seventeen.
Group Activities
-- Pick 2 or 3 coins from 1p to 20p; choose an efficient order to add, then find the total.
-- Find the total of all possible combinations of three coins 1p to 20p. Add four coins.

Day 2 Teaching
Label objects with price tags from 20p to 30p. Use a 0–30p penny line to show how to find change from 30p if paying for an item with a 20p and a 10p coin. Choose an item and count up from its price to 30p. Repeat.
Group Activities
-- Role-play ‘shops’, finding the change from 30p.
-- Work out whether a shopkeeper has given the correct change.

Day 3 Teaching
Display stickers priced between 10p and 30p. Which stickers can’t be bought with 20p? Demonstrate how to use the ‘friendly pairs’ cards (the bonds to 10) to help work out the change from 20p when buying different stickers: recalling and using number bonds, rather than counting up in 1s.
Group Activities
Use the in-depth problem-solving investigation ‘Change Challenge’ as today’s group activity.
Or, use this activity:
-- Look for friendly facts and pairs to help work out change.
