Lesson 3: Investigating Rate of Change and Slope
Duration of Days: 4
Lesson Objective
Students will understand that slope and rate of change are interchangeable and learn to calculate slope between two points.
What is the relationship between an equation and its graph?
What does the slope represent in a real-world scenario?
slope
unit rate
8.EE.B.6: Use similar triangles to explain why the slope m is the same between any two distinct points on a non-vertical line.
Students will introduce the word "slope" to replace "rate of change" as they become interchangeable. They will practice finding the slope between two points and interpreting it in context. (DOK 2)
Difficulty seeing that rate of change and slope are the same concept.
Computational errors when using the slope formula between two points.
Drag and drop or matching activies.
