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
