Outcomes

6.RP.A.2

Understand the concept of a unit rate a/b associated with a ratio a : b with b ≠ 0, and use rate language (e.G., For every, for each, for each 1, per) in the context of a ratio relationship. (Complex fraction notation is not an expectation for unit rates in this grade level.)

6.RP.A.3b

Use ratio and rate reasoning to solve mathematical problems and problems in real-world context (e.G., By reasoning about data collected from measurements, tables of equivalent ratios, tape diagrams, double number line diagrams, or equations). Solve unit rate problems including those involving unit pricing and constant speed.
