Rotational Symmetry Game
Learn to recognize symmetry in this fun card game! The more your child practices, the better he'll get at recognizing this special characteristic many playing cards have.
Symmetry is a balance that frequently occurs in nature and in many familiar places. There are three types of symmetry. For the purposes of this game, we'll focus on rotational or point symmetry. If a figure can be rotated less than 360o so that it coincides with itself, it has rotational symmetry. For example, the three of diamonds has rotational symmetry, but the five of hearts does not. (Notice that when you turn the five of hearts 180o, the center heart is turned upside down.)
