Reflection: Developing a Conceptual Understanding Slope & Rate of Change - Section 2: Guided Notes + Practice


In this lesson my students struggled the most with integer computation. Accuracy is very important in this lesson, so I make many counter chips and number lines readily available for students as they work through each problem.

My students moved quickly through this lesson, so I had a few minutes of extra time at the end of class. This time will be used to support student's understanding of slope with visual examples on the Desmos graphing calculator. I will graph the following four linear functions, "f(x) = 2x + 3", "f(x) = 1/4x + 3, f(x) = -5x + 4, and f(x) = 1/3. I will ask students to make a connection between the visual representation of each line in relation to the value of its slope. I also used Desmos in combination with the formula of slope to explore horizontal and vertical lines.

Slope & Rate of Change

Unit 2: Linear & Absolute Value Functions
Lesson 6 of 10

Objective: SWBAT calculate the rate of change in a linear equation.

Big Idea: Students will interpret the rate of change in the context of a problem, and use it to make predications about a situation that shows linear growth.
