Learning the proper term for solid shapes at an early age gives your child a head start in geometry. It’s very simple to teach them some proper names.
- Call a can a cylinder.
- Call dice or square boxes a cube.
- A CD case or a cereal box is a rectangular prism.
- A ball or a globe is a sphere.
- A cone shape at the primary level is just like an ice cream cone.
- A pyramid can easily be shown to a child courtesy of almost any book on ancient Egypt.
If you use the objects proper name and then its “household” name interchangeably, children can learn about a variety of 3D solid shapes before they enter kindergarten.
To take this lesson to the next level, talk about the number of sides (faces) of a shape, the number of corners (vertices) and what shapes have common attributes. Does it roll? Can you slide it? What shape appears if you trace around the bottom of it with a pencil.
