Drag Racer Dragonfly

Seventh Grade Poster Problem
Ratios and Proportional Relationships

This lesson gives students the opportunity to work with situations that represent three types of rate problems:

  1. How much time? In this situation, students need to determine how long it takes the dragonfly to fly a specific distance.
  2. How far? Here, students need to find the distance the dragonfly flew in a given time.
  3. How fast? In this case, students need to figure out the rate at which the dragonfly is flying.

Learning Objectives:

  • Determine whether two quantities are in a proportional relationship.
  • Solve problems by determining missing values in a proportional relationship.
  • Identify the constant of proportionality (unit rate) in tables, graphs, equations, diagrams, and verbal descriptions of proportional relationships.
