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
