$24 per paid hour; ask whether 5 hours should give $29, $120 or another amount. - Model · 4 min. Teacher writes
5 paid h × $24/paid h = $120; cancel hour units aloud and estimate five twenties ≈ $100. - Guided trial · 5 min. Calculate 3 hours = $72 and 7 hours = $168; ask why adding 24 once is insufficient.
- Independent card · 7 min. Learners calculate 2, 5 and 6 base paid hours, each with expression, units and one reasonableness sentence. Calculator permitted after estimate.
- Check · 4 min. Partner tests whether 6 hours is more than 5 by exactly $24 and corrects a missing unit label.
- Exit · 3 min. Key: five hours $120; six hours $144; the difference is one $24 paid hour. “Paid” matters because breaks are unspecified.
