Display the two prices side by side as pupils settle. Take three hands-up answers, not open call-outs. You are only fishing for the idea that the digits after the point are the cent — the naming as hundredths comes in the next step, so don't correct or extend yet.

€1.50: €1 coin and 50c. One whole euro plus 50c, which is half a euro, so one and a half euro.

€0.25: coins (20c + 5c) add to 25c but don't look like a quarter — use a fraction wall beside the tray, point to the one-quarter piece as you say 25 out of 100 cent is one quarter.

Take the hands-up prediction before moving on: if a quarter is 25 cent, how much is half a euro? Wrong guesses are fine.

All three trays show at once — create the reveal by moving your finger, not by the screen changing.

€2.75: two whole euro plus 75c left over. 75 out of 100 cent is three quarters, so two and three-quarter euro. The cent part is always a fraction of just one euro.

Metre parallel: hold up a real one-metre length. State one metre is 100 centimetres, just as a euro is 100 cent. Fold it in half in front of the class — each part is 50cm, half a metre, the same as €0.50 is half a euro. Cent and centimetres are both hundredths of one whole. Do this physically before pupils convert on paper.

This round is for talking it through together — pupils take turns at the board and the class agrees or corrects out loud.

Call each amount, send an individual pupil to drag the coins, and have the class read the total two ways: the decimal (zero point five zero) and the fraction (half a euro). To keep the watching rows thinking, before each pupil drags ask the class which coins will we need, and how many? and take two hands-up answers. Watch for the zero in €3.05 — pupils often drop it and read three-fifty; say three euro and five cent aloud first. Rotate four pupils.

These are the practice questions — pupils take turns at the board, check each answer, and the class confirms before moving on. Keep the board work brisk rather than over-explaining.

For the change question, count on from €3.50 up to €5 aloud with the class. For the 75-cent question, revoice: a whole euro is 100 cent, so 100 take away 75 leaves 25 — that is what is missing to make a full euro. For the metre question, revoice: each tenth of a metre is 10 centimetres, so 0.3 m is 3 tens, which is 30 centimetres. Individual pupils solve each while the rest predict and call out.
