From Ratio Tables, Equations and Double Number Line Diagrams to Plots on the Coordinate Plane

Represent ratios using a variety of methods. Classmates combine the representations of ratios previously learned with the coordinate plane. Using ratio tables, equations, double number lines, and ordered pairs to represent ratios, they employ the different representations to solve problems in the 14th segment in a 29-part series.

Instructional Ideas
  • Lead a discussion on when to connect points and when not to
  • Stress the importance of labeling the graph
Classroom Considerations
  • The class should know how to plot points in the coordinate plane
Pros
  • The answer key shows the graphs
  • Contains anticipated responses to discussion questions
Cons
  • The lesson notes refer to non-integer data used in the lesson though all data points are integers
