I began the class by talking about geometry and, specifically, the geometry of movement. While doing so, I used Sketchpad to do the following transformations while I defined them on the board:
Types of Transformations
- Dilations (which they had done with the Wumps worksheet previously)
- Rotations
- Reflections
- Translations (which they will do today)
Then I went through the PowerPoint presentation with them writing the rules (using ordered pair notation) as we went along. The lesson was only about 15 minutes, much of it with Sketchpad. Then they worked on their homework which was 3, 6b, 7 – 13 from the textbook.
