Title – Slopes and Rate-of-Change
By – Mikel Whiting
Primary Subject – Math
Duration: 90

Overview: This lesson is about determining the steepness of slopes and the rates of change.

Lesson Plan Objectives:
MA.C.3.4.2 Using a rectangular coordinate system (graph), applies and algebraically verifies properties of two- and three-dimensional figures, including distance, midpoint, slope, parallelism, and perpendicularity.

Measurable Objective(s)
In this lesson students will learn to: 1. investigate real-world situations that relate to slopes and rates of change, and 2. determine the steepness of slopes by viewing and recording data.

Motivational Activity
(15 min.) MODELING: Tell the students that on each table are construction paper and markers. Assign students to teams of four and have them work as a team to make paper airplanes. Have half of the group members to fly the planes and the other members to time the flights in seconds. Have the students to graph their data in the form of sloping lines. Have students turn in their airplanes in fifteen minutes. Students are to find three sloping objects and determine the difference in their “rise” and “run”.
