Fractions and Decimals in Money and Measure

Learn how money amounts and measurements use decimals and fractions. Discover that 50 cents is half a euro, 25 cents is a quarter, and centimetres work the same way as part of a metre.

Warning: Your screen size is quite small for viewing this. Rotate your device into landscape mode if you can.

1 - Getting Started ~4 mins

Illustration for Getting Started Here are two shop prices: €1.20 and €2.50. Look at the part after the point on each one. What do you think those two little digits are counting — and what does the €2.50 really mean when you say it out loud?

👇 Mark your steps as done as you complete them.

2 - Watch and Notice ~10 mins

Three trays of coins are on screen, each with an amount to read. The two digits after the point count the cent, and there are one hundred cent in every euro. Look at the cent part of each amount as we name it as a fraction of a euro.

👇 Mark your steps as done as you complete them.

3 - Try It Together ~8 mins

Key point

Let's build four amounts together on the coin tray and read each one two ways — as a decimal, then as a fraction of a euro: €0.50, then €1.30, then €0.75, then €3.05. The €0.50 lands exactly on half a euro, and the €3.05 has a tricky zero we will say aloud before we check it.

Build the amount and read it

4 - Write the Amount in Your Copy ~2 mins

COPYBOOK MOMENT

In your maths copy, write €0.50 as one half of a euro and €0.25 as one quarter of a euro. Then write 0.5 m as fifty centimetres. Say each one to yourself as you write it: half a euro, a quarter of a euro, half a metre.

5 - Class Challenge ~9 mins

Key point

Let's work through four money and measure problems together, each a step harder than the last: add up two 60c snacks; find the change from a €5 note for a €3.50 book; work out how much less 75 cent is than a full euro of 100 cent; and change 0.3 m into centimetres. The last one reminds us that centimetres are hundredths of a metre, just like cent are hundredths of a euro.
