Suggestions for Follow-up Actions (KS3-MS8-2)
Possible problems in students' learning (for reference only)
- Students could not imagine how the cube overlaps the original cube when rotated about an axis of rotational symmetry
- Students do not recognize the difference between the axis of rotation and the axis of rotational symmetry
- Students do not know how to name the axis of rotational symmetry

Rotational Symmetry of the Cube |
Recognize the concept of axes of rotational symmetry of the cube | In the activities in the worksheet, students could drag the axis of rotation to different positions and then rotate the cube to investigate the rotational symmetry. Through these activities, students could recognize the rotational symmetry of the cube and the definition of axes of rotational symmetry. |
