What students learn

In this lesson, students understand ratio concepts and use ratio reasoning to solve problems.

  • Understand the concept of a ratio and use ratio language to describe a ratio relationship between two quantities.

  • 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.

  • 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.
