Hands up: how many different ways can you think of to make exactly 80c using coins? Is there just one way, or more than one?
Here are four amounts. Read each total and say which coins and notes could make it. Then we tap those coins onto the tray and check that the total matches.
The last one hides a trap. Look at €3.05: the number straight after the point is a zero, so say it as three euro and five cent. The zero is in how the amount is written; you can still use 10c, 20c or other coins as long as the total is right.
Now we build these amounts on the coin tray, in this order: 55c, then €1.15, then €2.40, then €3.08. One pupil taps the coins at the board while everyone else watches the running total and agrees or corrects out loud. The last one, €3.08, has a zero straight after the point, so say it as three euro and eight cent before we check it.
In your maths copy, write two different ways to make €1.55. List the coins and notes in each way, one under the other, then add each list up to check both come to €1.55.
