- Plot Points
- Reflection
- Rotation
- Translation
- Transformation
About the Lesson
Students place their right hand on a grid, trace it and then plot points along this trace. These points are plotted on the calculator to form a digital image, in so doing students practice recording points on the Cartesian plane. These points are then reflected in the y axis to form a the left hand, followed by a series of other transformations.
