Books

Everything in the material world has shape. However, in mathematics, the focus is very much on regular shapes, such as the two-dimensional circle, triangle, and rectangle (including everyone’s favorite rectangle, the square) and the three-dimensional solids known as spheres and polyhedrons (that is, geometric solids with flat faces and straight edges). In our everyday world, these solids commonly appear in objects we describe as boxes, pyramids, blocks, cylinders, and balls. Children in a math-rich early childhood environment will have many experiences working with shape, and the books they interact with can help further discussions, helping them to think deeper about the attributes of different shapes.
