Identify and Sort Solid Shapes

As children begin their study of three-dimensional, or solid, figures, they'll see that many of these figures have faces, or flat surfaces, that are familiar. For example, two surfaces of a cylinder are circles; each of a cube's six faces is a square. Children explore, identify, and describe many three-dimensional figures: cylinders, spheres, cones, cubes, pyramids, and rectangular prisms. These shapes are familiar because they appear often in the environment—as cans, balls, ice cream cones, number cubes or dice, monuments and buildings, and boxes, respectively. Children can use these kinds of shapes as a basis for sorting. They can also sort figures according to whether they are solid or flat, have flat or curved surfaces or both, or according to the ways they can move (slide, roll, or both).
