Instructor Overview

Students work with a set of cards showing different ways of expressing ratios numerically. They group the cards showing equivalent ratios and then order the groups from least to greatest value.

Key Concepts

It can be hard to compare the values of ratios represented in different forms (e.g., a:b, decimal, fraction, a to b). Simplifying ratios makes it easier to compare and order their values.

Goals and Learning Objectives

  • Identify ratios that are equivalent but expressed differently.
  • Simplify ratios in order to group and order cards efficiently and successfully.
