Module 2 Lesson 19

  • Divide two- and three-digit dividends by multiples of 10 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.


I can divide two- and three-digit dividends by multiples of 10 with single-digit quotients and make connections to a written method.
