Unit 2, Lesson 12# Estimating Digits in a Quotient

EngageNY 45 min(s)

Students connect estimation with place value in order to determine the standard algorithm for division. Teaching estimation is an excellent way of extending place value concepts to large numbers and decimals. These skills include place value concepts for four- and five-digit numbers, multiplication by two-digit numbers, and estimating division by two-digit numbers. This lesson focuses on estimating division by two-digit numbers first by rounding to one-digit arithmetic facts.
