AL.RP. Ratios and Proportional Relationships – Students will:
Understand ratio concepts and use ratio reasoning to solve problems.
RP.1. Understand the concept of a ratio, and use ratio language to describe a ratio relationship between two quantities.
RP.3. Use ratio and rate reasoning to solve real-world and mathematical problems, e.g., by reasoning about tables of equivalent ratios, tape diagrams, double number line diagrams, or equations.
RP.3.a. Make tables of equivalent ratios relating quantities with whole-number measurements, find missing values in the tables, and plot the pairs of values on the coordinate plane. Use tables to compare ratios.
