My son knows basic shapes. What shapes should I teach him next?

If your child already easily recognizes squares, circles, triangles, and rectangles, he may be interested in learning about other 2-dimensional shapes and some basic 3-dimensional shapes. Your child may be excited to learn that a shape with 5 sides is called a “pentagon” and a 6-sided shape is called a “hexagon”. In addition to flat, 2-dimensional shapes, you could introduce your child to the names of some 3D shapes such as spheres, cubes, cylinders, and cones. As you and your child search the world around you for these 3D shapes, you may be surprised to find them all around you!
