6.RP.A.2 lessons
Understand the concept of a unit rate a/b associated with a ratio a : b with b ≠ 0, and use rate language in the context of a ratio relationship.
The Common Core State Standards for Mathematics code 6.RP.A.2 asks students to: “Understand the concept of a unit rate a/b associated with a ratio a : b with b ≠ 0, and use rate language in the context of a ratio relationship.” These Fieldbook lessons teach it hands-on, with everyday materials, a printable teacher guide and a student sheet.
Mix It, Pace It: Ratio, Rate and Percent Grades 6–7
- Who walks fastest? 50–60 min
Students time themselves walking 20 m and count their steps, then work out metres per second, steps per second and metres per step. The surprise: the walker who takes the most steps per second is often not the fastest. Students explain rates and unit rates, compare them, and convert metres per second to kilometres per hour.
- Which is the better deal? 45–60 min
Teams shop from printed store cards, working out the price of one notebook or one litre to find the real best buys, and discover that the bigger package isn't always cheaper and the bigger percent off doesn't always save more money. Students use unit prices, percent as a rate per 100, and find a part, a whole or a percent.
