TEN IDEAS FOR BUILDING UNDERSTANDING FOR SLOPE OR RATE OF CHANGE Jim Rahn

Ask your students to describe their understanding of slope.

What might an initial lesson in slope look like? Compare the steepness of lines Idea 1

How can we numerically describe the steepness or slope of a line? Visualize the rate of change or the rise over the run Idea 2

Develop Rise over Run from Visuals Idea 3

Present Slope or Steepness of a Line in a Real World Context Idea 4

Calculate Rate of Change from Charts? GBD5 GBD6 Idea 5

Study Rates of Change in Different Tables for the Same Function GBD7 GBD8 Idea 6

I Have… Who Has… with Slope Idea 7

Use the Transformation App with Graphs Idea 8 Use both graphs and transformations to understand rate of change

Use the Transformation App with Graphs and Tables Idea 9 Use both graphs and tables to understand rate of change GBD 9

Engage Students in Comparing Slopes Idea 10 Collect data, analyze data, and compare rates of change or slope
