1 - Getting Started ~4 mins

Here are two prices: €1.20 and €1.02. They both use a 1, a 2 and a 0.

Look at the coins that make each one. Are they the same amount of money? If not, which one buys more, and by how much?

👇 Mark your steps as done as you complete them.

2 - Watch and Notice ~9 mins

Each tray on the interactive holds real coins for one price. Read the coins together and notice which column each coin sits in. Same digits can mean very different money depending on where they sit.

👇 Mark your steps as done as you complete them.

3 - Try It Together ~11 mins

Today we build these amounts together on the coin tray: first €0.85, then €1.20, then €1.02, then €3.06. We say the running total aloud as each coin drops, and we watch the trailing zero appear or vanish in the standard form each time.

Build the amount together

4 - Write the Amount in Your Copy ~2 mins

COPYBOOK MOMENT

In your maths copy, write each of these money amounts in standard form (€X.XX), one under the other:

€1.20
€1.02
€4.55
€9.99

Then circle the cent column on each one to check for the trailing zero.

5 - Class Challenge ~8 mins

Today we work through these targets on the board, in order: €1.20, then €1.02, then €4.55, then €9.99. The last one is one cent short of ten euro, so it needs the most coins — that is the challenge to finish on.

Make the target amount
