Using Geometer’s Sketchpad to Explore Transformational
Geometry
iLearn Grade 8
Math Session 8.2
Focusing Questions
What are other strategies of teaching transformational geometry?
How can Geometer’s Sketchpad support working with transformations?
Instruction
Framing The Session
You have used the SmartBoard and virtual protractor to do transformations. Now, you will focus on using Geometer’s Sketchpad to accomplish this.
Teaching
Open to page 290, PS A, in “IMPACT.”
Together we will follow the steps in the handout “Steps to Modify a Premade GSP Sketch” to complete the Problem Set.
Guided Practice
Open Reflection.gsp.
Create instructions and questions for page 293 of “IMPACT Math” directly in Geometer’s Sketchpad using the text tool.
Work Time
Getting Started
Working in small groups, explore the following sketches and discuss how they relate to the problem sets indicated.
