6.RP.A.1
Understand the concept of a ratio and use ratio language to describe a ratio relationship between two quantities. For example, "The ratio of wings to beaks in the bird house at the zoo was 2:1, because for every 2 wings there was 1 beak." "For every vote candidate A received, candidate C received nearly three votes."
Students will learn how to find the ratio between two things. They'll learn how to find ratios from images, tables, and word problems. Conclude by giving your students this challenge.
