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: Students define line symmetry. Students fold paper in half and paint a design on one side of paper. Students fold again and identify where the line of symmetry falls. Literature Connections: Who's There?
