My Math Chapter 3: Divide by a One-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 4: Divide by a Two-Digit Divisor.

Chapter 3 Objectives:

• Model division using base-10 blocks
• Divide by powers of 10 (division fact extensions)
• Estimate quotients of whole number division
• Apply the distributive property to division
• Use an algorithm to divide whole numbers.
• Interpret remainders of division word problems
