It will be fun to create symmetry with small toys or objects. Place a ruler or a stick vertically on a surface. Your child can place the toys or objects in a certain pattern on one side, maybe arranged in a design or by color. Then he or she can create the same pattern on the other side. It can be fun to play this as a game with two players. One player closes his or her eyes while the first player creates the design on one side. Once he or she is finished, the second player opens his or her eyes and must create the symmetrical design on the other side. The only catch to this activity is having enough objects to create two matching sides!
