Hook lesson with online Tetris Game! Followed by an activity where students will move a Tetris piece with a series of translations and reflections. Students will record starting coordinates and image coordinates to look for patterns and discover what happens to x and y-coordinates when these transformations are performed. Students are asked to draw conclusions and make predictions based on their conclusions. The product also includes a graphic organizer and examples that can be teacher-led as a wrap-up activity, followed by a brief practice worksheet. Problems include writing a rule for translations and reflections, writing new coordinates with a given rule, and using coordinates to identify a transformation and then applying it to a new point.
Designed as part of a Geometry unit on congruence.
