Line Symmetry

  1. You will need Geoboards and dot paper for this activity.
  2. Have your students make a line through the middle of the Geoboard using a rubberband. They can do this horizontally, vertically, or diagonally.
  3. They then should make a shape on one side of the line with one side touching the line.
  4. Have them then draw the mirror image of the shape on the other side of the line.
  5. After practicing with the geoboards, have them do this same exercise, using different lines of symmetry and different shapes, on dot paper.
  6. They can use a mirror to check themselves.
