Finding the Endpoint of a Segment Given One Endpoint and the Midpoint

Activity Overview

The purpose of the activity is for students to verify how to determine the coordinates of an endpoint of a segment, given the midpoint and other endpoint, using the dynamic capabilities of Cabri Jr.

Before the Activity

You will need to transfer the application variable MIDENDPT.8xv to each student calculator. You can do this through a TI-Navigator system, or you can download the file onto your calculator using TI Connect and then link your calculator to each student calculator.

During the Activity

Give each student a copy of the student handout. You should allow 10-15 minutes for the students to work though the handout.

After the Activity

Review student answers:

  • As a class, discuss questions that appeared to be more challenging
  • Re-teach concepts as necessary
