Instructional Ideas
- Use either transparency sheets or tracing paper to trace and rotate the image
- Challenge pupils to identify a pattern of the coordinates in rotations of multiple of 90 around the center
Classroom Considerations
- Some instructions on rotations include either clockwise and counter-clockwise
- The lesson is the fifth in an 11-part unit on congruence and similarity
Pros
- The independent practice has a section in which pupils need to analyze the affects of a rotation
- The handout and the key use colors to distinguish between the pre-image and the image
Cons
- The lesson does not rely on a variety of instructional methods but sticks to direct instruction
