Unit 4, Lesson 31# Divide decimal dividends by non‐unit decimal divisors.

EngageNY 60 min(s)

In this lesson, students continue understanding division of decimals by combining strategies. Students rewrite decimals as fractions. For example, 34.8 ÷ 0.6 = 34.8/0.6. Then they multiply by a fraction equal to 1 to get a whole number denominator, while reasoning to get numbers that are easier to compute. For example, 34.8/0.6 x 10/10 = 348/6. Then they estimate a reasonable answer and use long division to get the final answer.
