Estimate and Check Answer Key

This worksheet guides students through estimating division problems by rounding the dividend to the nearest ten, hundred, or thousand and then checking the estimate by dividing exactly. Each problem requires two steps: producing an estimate using rounding strategies and confirming accuracy through precise computation. This dual-process task builds number sense by helping learners understand how place-value rounding affects quotients. Students practice mental estimation skills while also demonstrating mastery of dividing by 10, 100, and 1,000. The worksheet strengthens reasoning, encourages comparison between estimated and actual answers, and helps students evaluate the reasonableness of results. It is useful for developing flexible thinking and for reinforcing the relationship between rounding and division.
