Estimating Products by Rounding - Round factors to greatest place value - then multiply

Sep 30, 2026

Uploaded by Ben

Estimating Products by Rounding practices estimating multiplication by rounding each factor to its greatest place value and then multiplying the rounded numbers. The worksheet provides problems such as 999 × 6, 18 × 96, and other two-digit or three-digit combinations, asking students to compute an approximate product. An answer key section lists the rounded estimates (e.g., 999 × 6 ≈ 6,000) to support checking and targeted feedback on estimation accuracy.
