Lesson 14

Math

Unit 1

6th Grade

Lesson 14 of 18

Objective


Solve ratio problems using different strategies.

Common Core Standards


Core Standards

  • 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."
  • 6.RP.A.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.
  • 6.RP.A.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.

Criteria for Success


  1. Choose and apply efficient strategies from toolkit in order to solve ratio problems (MP.5).

Tips for Teachers


This is a flex lesson that can be used in a variety of ways, depending on the individual class. There are no Anchor Problems, as teachers can determine what specific concepts are best to look at with the whole class. The Problem Set Guidance is a collection of problems and activities that may be used for this day.
