Take three hands-up answers, not open call-outs. Write two or three of the pupils' coin sets on the board side by side so the class can see the same total made different ways. Do not settle on a 'best' way yet — that is the point of the lesson.

Read each total in euro and cent as a class.

• 45c — two 20c and a 5c; ask what other set would also make 45c.
• €1.30 — a €1 coin, a 20c, a 10c; the fewest pieces for this amount.
• €2.75 — show one build, then ask the class for a second way before moving on.
• €3.05 — the zero straight after the point is the point; there is no 10c or 20c here, just single cent.

Point at each coin as the class tallies aloud; these are static snapshots, nothing to drag.

Talk this one through together — one pupil builds at the board and the class agrees or corrects out loud.

An individual pupil drags coins to build the called amount while the class watches the running total. After each build, ask if a larger coin would have used fewer pieces. On €3.08, hold out for the eight single cent and the zero straight after the point — this is the same trap as €3.05 in the model.

This is the practice round — 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 each target ask the class to predict the largest coin or note to reach for first. €3.70 rewards the largest-first idea neatly — the fewest way is a €2, a €1, a 50c and a 20c; take predictions before the reveal.
