What this practises: money. Pupils put coins and prices in order, make the same amount with different coins, add up orders, find change by counting on along a number line, and give change in the fewest coins. Everything is set at an invented school summer fair.
Print: this sheet, one per pupil, and the stimulus sheet “Ysgol Bryn Celyn summer fair: the Welsh cake stall”, one between two. No computers are needed. No real money is needed. Play coins are optional; some pupils find them helpful.
Run: 5 min read the stimulus sheet aloud · 7 min Step 1 · 7 min Step 2 · 8 min Step 3 · 12 min Step 4 · 7 min Step 5 · 9 min Step 6. Total 55 minutes. Before Step 4, go through the number line example with the class.
Collect: this sheet. Quick checks: coins in order 1p, 2p, 5p, 10p, 20p, 50p, £1, £2. Step 3 totals: Cerys 55p, Osian 80p, Mali £1.05, Dewi £1.35. Step 4 change: 15p, 45p, 20p, 95p, 65p. The worked example has every answer.
You are a helper on the Welsh cake stall at the Ysgol Bryn Celyn summer fair. Customers buy cakes and drinks. You need to add up what they buy, take their money and give them the right change. Look at the stimulus sheet for the prices and the coins.
(a) Look at the coins on the stimulus sheet. Write them in order of value. Start with the coin that is worth the least.
| Least | Most |
|---|
(b) The 2p coin is bigger than the 5p coin. Which one is worth more? ______________
(c) Write the 9 things on the price board in order. Start with the cheapest.
| Order | Item | Price |
|---|---|---|
| 1st | ||
| 2nd | ||
| 3rd | ||
| 4th | ||
| 5th | ||
| 6th | ||
| 7th | ||
| 8th | ||
| 9th |
(d) Write < (less than) or > (more than) in each box.
| Slice of bara brith (45p) | Cupcake (40p) | |
| Bag of 4 Welsh cakes (£1.10) | Jar of strawberry jam (£1.50) | |
| Whole bara brith loaf (£3.75) | Jar of strawberry jam (£1.50) |
(e) Iolo says, “The jam costs less than the flapjack, because 1 is less than 35.” Is Iolo right? Explain.
Pay for each item in 2 different ways. Draw the coins as circles with the value inside, or write them like this: 20p + 10p.
| Item | Way 1 | Way 2 |
|---|---|---|
| Welsh cake (30p) | ||
| Cup of lemonade (25p) | ||
| Slice of bara brith (45p) | ||
| Bag of 4 Welsh cakes (£1.10) |
Look at your 2 ways for the bara brith. Which way uses fewer coins? ______________
Add up each order. Show your working. Remember 100p = £1, so 120p = £1.20.
| Customer | Order | Working | Total |
|---|---|---|---|
| Cerys | Welsh cake, cup of lemonade | ||
| Osian | Cupcake, apple, cup of lemonade | ||
| Mali | Slice of bara brith, 2 Welsh cakes | ||
| Dewi | Bag of 4 Welsh cakes, cup of lemonade |
To find the change, count on from the price to the money paid. Jump to the next 10 first, then jump in bigger steps.
Example: Nia buys an apple for 15p. She pays with a 50p coin.
15p to 20p is 5p. 20p to 50p is 30p. 5p + 30p = 35p. Nia gets 35p change. “Diolch!”
Now do these. Draw your jumps on each number line.
(a) Rhys buys a flapjack (35p). He pays with a 50p coin.
Change = ______________
(b) Cerys’s order costs 55p. She pays with a £1 coin.
Change = ______________
(c) Osian’s order costs 80p. He pays with a £1 coin.
Change = ______________
(d) Mali’s order costs £1.05. She pays with a £2 coin. Tip: £1.05 is 105p and £2 is 200p.
Change = ______________
(e) Dewi’s order costs £1.35. He pays with a £2 coin.
Change = ______________
The stall rule says: give change in the fewest coins. Start with the biggest coin you can.
| Change | Coins | Number of coins |
|---|---|---|
| 15p | ||
| 45p | ||
| 20p | ||
| 95p | ||
| 65p |
Think: Tomos gave 45p change as 10p, 10p, 20p, 5p. That is 4 coins. Is it the right amount? Could he use fewer coins? How?
(a) Elin has £1. She wants a cupcake, a slice of bara brith and a cup of lemonade. Does she have enough money? Show how you know.
(b) Gethin has £1. How many single Welsh cakes can he buy? How much change does he get?
(c) Now you have £1. Choose at least 2 things from the price board. Fill in the table.
| Item | Price |
|---|---|
| Total | |
| Change from £1 | |
| Change in the fewest coins |
