  1. 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.

  2. 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.

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

  4. Activate Knowledge Round the divisor to the nearest 10 908 ÷ 28

  5. Activate Knowledge Name the multiple of 30 that’s closest to 908 908 ÷ 28 908 ÷ 30

  6. Activate Knowledge Below 900 ÷ 30, write the answer 908 ÷ 28 908 ÷ 30 908 ÷ 28 ≈ 900 ÷ 30
