What's in the worksheet

6 multiple-choice questions - Four notebooks at 25 baht paid with 200: 100 change - 120 students in 4 classes with 15 boys each: 15 girls per class - 20 baht a day for 15 days, 100 spent: 200 left - 8 boxes of 12, 40 given out: 56 left - 5 dozen is 60

How to use it in class

Use after teaching two-step problems, 8-10 minutes, team mode; teams write steps 1 and 2 separately before answering. - For the 120 students, reread the problem and stress that it asks for girls per class - The rectangle and dozen items are one-step, a breather between harder ones - Play it linked to the class to record results in the mark book, then use the per-question view to see which step pupils miss

Common sticking points

- For the 120 students, pupils who find all the girls get 60, not an option, because the Thai prompt does not say "per class". Accept that reasoning - Choosing 66 or 46 for 8 boxes of 12 after slipping on 12 × 8. Split into 10 × 8 + 2 × 8 - Choosing 220 or 180 for the 15-day savings after slipping on 20 × 15. Think 20 × 10 + 20 × 5
