A symmetry matching game idea is to draw three shapes that are symmetrical, as fast as they can, once the teacher says go. The shapes that are drawn must have a symmetrical match when the shape is divided into two equal parts. Examples of symmetrical shapes include circles, squares and hearts. The first student to draw a set of three symmetrical shapes first wins.
Prepare cutouts of shapes on heavy card stock. Then, cut the shapes into two equal parts based on the dividing line that makes them symmetrical. Scatter the partial shapes all over the floor. The game is for students to match the symmetrical shapes. For instance, if the preschooler picks up half of a rectangle, he must search for the other half of the rectangle, as opposed to picking up half of a circle or half of a triangle. The student that finds the most matched shapes first wins the game.
Create a symmetry matching game using file folders, which make cost effective and convenient game boards. For each student in your preschool class, make a chart of different colored hearts. Draw a line on each heart. Make some of your lines zigzags and some of them straight down the middle. The object of the game is for the preschooler to circle the shapes that have symmetry based on the dividing line. Students must look for the heart that can be folded in half on the line to create two equal parts. You can play this game with other shapes too.
Tell your students to stand or sit in a circle in the middle of the classroom. Pass out shapes made out of card stock, cut in half and glued to a wooden stick, to your preschoolers. Each half shape has a symmetrical partner that it is missing. Instruct students to walk around the room, keeping their shapes held high. The kids must look for the person who has the corresponding symmetrical shape that matches the one they have. When the preschoolers find their partners, they must stand together in a corner of the room.
