Take three hands-up answers, not open call-outs. Listen for whether pupils take away or count up — both can reach 70c. Revoice a count-up answer to seed the lesson: so you started at €1.30 and counted on to €2.

Point to each coin as you count on aloud. For the first tray say 70, 90, 100 — that's 20c to €0.90 and 10c to €1, so 30c change, touching the 20c then the 10c as you go. For the €5-from-€3.45 tray, land on €3.50 first, then €4, then €5 — hold out for the three separate hops. The bridge to the next euro is the move to make stick: crossing several euro is easy once you reach the whole euro first.

Talk this one through together — pupils take turns at the board and the class agrees or corrects out loud.

Have the pupil at the board start at the price each time and drop change coins onto the tray while the class counts aloud. For the €3.85 item say 15c to €4, then €1 to €5 — €1.15 change. Watch for pupils who reach for subtraction on the tricky one; steer back to the count-on hops. Rotate four pupils.

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.

Pupils count on to find the change; the tool records it as a subtraction (choose subtract, then type the change), but the thinking stays counting on. Before the two multi-euro items, model writing the change in cent: count on to €2.25, then say that's 225c, so pupils know what to type. The four items land at: 60c → 40c change (the tidy one, worth pausing on), €1.40 → 60c, €2.75 → €2.25 (225c), and €3.85 → €1.15 (115c). Revoice the count-on hops on the last two before checking.
