  Line Symmetry
Objective: to show line symmetry using pattern blocks.

Manipulative Activity: An object has line symmetry if, when you draw a line down the middle, the left side is a mirror image of the right side. Distribute pattern blocks and have students create designs that have line symmetry.

Technology Activity: Students will use a pattern block applet written by Jacobo Bulaevsky to reinforce the idea of line symmetry.

Have students go to Line Symmetry.

Paper/Pencil Activity: Depending on the level of your students, you can have them complete this activity individually or with assistance. Here are some possible activities:

  1. Students define line symmetry.
  2. Students fold paper in half and paint a design on one side of paper.
  3. Students fold again and identify where the line of symmetry falls.
