My Math Chapter 4: Divide by a Two-Digit Divisor

Updated 8-12-19

​In this chapter, students will use base-10 blocks to develop an algorithm for dividing whole number dividends by single-digit divisors. Note: This chapter will be combined with Chapter 3: Divide by a One-Digit Divisor.

Chapter 4 Objectives:
  • Model division using base-10 blocks
  • Divide by powers of 10 (division fact extensions)
  • Estimate quotients of whole number division
  • Use an algorithm to divide whole numbers with two-digit divisors.
  • Interpret remainders of division word problems
