Instructional Ideas

  • Use manipulatives and have learners discover the rules for multiples of 90-degree rotations
Classroom Considerations

  • Assumes individuals know the total degrees needed to rotate all the way around
  • It is helpful if pupils have learned about rotational symmetry
Pros

  • Uses colors to distinguish the image from the pre-image
  • Links to more resources on rotations
Cons

  • When originally referring to 180-degree rotation, the presenter places the figure into the wrong quadrant
