6th Grade Math - Rates - Lipman School

Clip 7/11: Lesson - Part 6 Lipman School


The teacher poses the question: Is there a way to compare the rates without doing all the division and decimals needed to find the unit rate? Is there a simpler way that wouldn't require using your calculator? Talk it over with your group. During whole class discussion, one group interprets a simpler strategy for simplifying the ratio and converts the three rates to steps per 5 seconds. Another student converts all the rates to steps per 60 seconds.

Teacher Commentary
