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
