Reflection: Developing a Conceptual Understanding Investigation of Distance and Time Graphs Using a CBR - Section 4: Exit Slip


An extension that I wanted to add to this lesson to develop a deeper understanding for students was to compare d=rt + 0 to y=mx + b. If time permits in a future lesson, I will have students write the equations of the lines from the distance-time graph as a piecewise function.  With m=r and d=y and t=x.  This extension would also help students not only see the relationship between the two formulas but also review how to write domain and range for the restricted line segments.

Investigation of Distance and Time Graphs Using a CBR

Unit 1: Introduction to Functions
Lesson 8 of 13

Objective: SWBAT analyze and draw the graphs of distance over time, as well as determine the increasing, decreasing, and constant intervals.

Big Idea: To match graphs to a student walking in real time to develop a conceptual understanding of distance over time and compare it to speed over time.
