Take two or three hands-up answers, not open call-outs. Push pupils to name the whole out loud (€60) before anyone reaches for the fraction. That single move heads off the most common slip in this lesson.

2/5 of €60: five equal parts, one part €12, two parts €24 for Aoife. Say it as divide by the bottom, multiply by the top.

3/4 of 2 litres: whole is the 2 litre bottle. Each quarter 0.5 l, three quarters 0.5+0.5+0.5 = 1.5 l, one quarter 0.5 l left. Stress the unit stays litres, not "2".

Spent 2/3 of €30: three parts of €10, spent €20, €10 still there. Ask "what fraction is left?" before revealing — this bridges to the remainder idea in the challenge.

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

Name the whole before each: €35, then 24 sweets, then €40. On the two-step voucher, pause after 'spends 1/2', because the whole for the next step is now €20, not €40. This is the key one of the round. Let a pupil predict the sister's share before you split the second bar, and confirm that Liam keeps the remaining 2/3 so nothing is left unaccounted.

Model the remainder trap on the board before copies open. Whole starts at €30. Spend 1/3: 30 ÷ 3 = 10, so €10 on the bus, €20 left. New whole is €20, not €30. Spend 1/2 of 20: 20 ÷ 2 = 10, so €10 on snacks. Check: 10 is less than 20, sensible. Slip to watch: using the original €30 for the second fraction.

Mystery answers, confirm aloud before the next clue: clue 1 €80 (120 ÷ 3 = 40, 40 × 2 = 80); clue 2 60 tickets (80 ÷ 4 = 20, 20 × 3 = 60); clue 3 50 yoghurts (60 ÷ 6 = 10, 10 × 5 = 50); clue 4 €40 (50 ÷ 5 = 10, 10 × 4 = 40); clue 5 €18 on fruit (first whole €40, 2/5 of 40 = 16 on bread, €24 left; new whole €24, 3/4 of 24 = 18). Check 18 is less than 24.

Pace brisk. On clue 5 let a pupil name the new whole before anyone multiplies. Close into the journal prompt.
