Display the three prices as pupils settle. Take three hands-up answers, not open call-outs. Hold out for pupils to name the two items and say roughly how much they'd spend, before anyone confirms the exact totals and the change from €5.

Read the price list aloud first so pupils have a fixed set of named items and prices to shop from all lesson. Then work through the three panels in order as subtractions from €5: point to each coin, don't drag.

Panel one buys the snack and fruit (€1.20 + €0.85 = €2.05), leaving €2.95. Panel two buys the drink and snack (€1.50 + €1.20 = €2.70), leaving €2.30. Panel three buys the dearest pair on the list, the drink and treat (€1.50 + €1.60 = €3.10), leaving only €1.90. Before revealing each remainder, ask the class to predict it. Draw out that the dearer the pair, the less is left.

This round is for talking it through together: pupils take turns at the board and the class agrees or corrects out loud before you move on.

Keep a running total on the board beside the tray: after the drink, €1.50; after the snack, €2.70; after the fruit, €3.55. Before the €1.60 treat, ask the class to predict whether it fits (€3.55 + €1.60 = €5.15, so it does not). Revoice a good answer: so we'd be over by fifteen cent. On the value-for-money pair, draw out that the €0.90 snack is better value only if it is the same size and just as good — cheaper is not always better if you get less. Rotate four pupils to lay out and read each price.

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.

The tasks rise in difficulty: the first is one subtraction from €2 (€2 − €1.20 = €0.80), the last asks pupils to compare prices on the list for best value before adding. On the third task, note that buying all four items (drink + snack + treat + fruit) would total €5.15 and so go over — dropping the fruit leaves the three-item drink + snack + treat basket at €4.30, the closest fit under €5. Fast finishers watch the board. Watch for pupils who tip over the budget and don't notice — get the class to spot it.
