Symmetry Projects There are many opportunities to notice, name, and discuss symmetry. The world is full of symmetrical objects, both natural and artificial. Look for objects that are symmetrical around the kitchen or outside while on a walk or a drive. You may want to continue exploring symmetrical designs with different art projects.

Two symmetrical objects. One object is an oven and a stove with 4 burners. The other object is an entryway with two doors that open from the middle.

Your child can print shapes with cut potatoes or sponges dipped in paint on one side of a sheet of paper, and then fold the paper in half. The design that results will be symmetrical around the fold. Paper-cutting is another way to create a symmetrical arrangement of shapes. Plain paper and tissue paper, or newspaper can be folded in quarters (or folded as many times as you like) and then cut and unfolded to create designs with more than one line of symmetry.
