Mastering Division: Dividing Three- and Four-Digit Numbers by Two-Digit Divisors

In this lesson, students will learn to divide three- and four-digit dividends by two-digit divisors. The focus is on understanding and reasoning about the decomposition of successive remainders in each place value. Aligned with Common Core Standard 5.NBT.6, the lesson emphasizes strategies based on place value and the relationship between multiplication and division. Students will engage with various models and learn to estimate, solve, and check division problems, ultimately enhancing their problem-solving skills in mathematics.

  1. Module 2 Lesson 23 • Divide three- and four-digit dividends by two-digit divisors resulting in two- and three-digit quotients, reasoning about the decomposition of successive remainders in each place value.

  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 three- and four-digit dividends by two-digit divisors resulting in two- and three-digit quotients, reasoning about the decomposition of successive remainders in each place value. Learning Targets
