Students complete nine multiplication and estimation problems including 73 × 18, estimating 67 × 42 by rounding to 70 × 40, and 91 × 24. The matching activity pairs 25 × 36, 48 × 22, 83 × 11, and 62 × 45 with their products.
Estimation alongside exact computation trains students to check whether their computed answers fall in a reasonable range.
