Grade 6 Mathematics Module 1, Topic C, Lesson 18

Studying for Test

Student Outcomes

  • While there is no physical way to divide two different quantities like (5 miles)/(2 hours), students make use of the structure of division and ratios to model (5 miles)/(2 hours) as a quantity 2.5 mph.  Interpreting a rate as a division of two quantities, or better yet a fraction, is the first step towards converting measurement units using rates later in the module, and dimensional analysis in high school.  They use this interpretation of a rate in word problems when multiplying a rate by a quantity.
