Module 2 Lesson 20 Divide two- and three-digit dividends by two-digit divisors with single-digit quotients and make connections to a written method.

Common Core Standards 5.NBT.6 Find whole-number quotients of whole numbers with up to four-digit dividends and two- digit divisors, using strategies based on place value, the properties of operations, and/or the relationship between multiplication and division. Illustrate and explain the calculation by using equations, rectangular arrays, and/or area models.

Learning Targets I can Divide two- and three-digit dividends by two-digit divisors with single-digit quotients and make connections to a written method.
