Unit 2, Lesson 21# Divide two- and three-digit dividends by two-digit divisors with single-digit quotients and make connections to a written method.

EngageNY 60 min(s)

In this lesson, students continue to solve division problems using the standard algorithm. They estimate quotients with three-digit dividends by two-digit divisors, by rounding to compatible numbers. For example, students answer 256 ÷ 47 by rounding to 250 ÷ 40. Then they solve the division problem using the standard algorithm and making connections between the two methods.
