Compare 2-Dimensional and 3-Dimensional Shapes
What's the relationship between a triangle and a pyramid? A circle and a cylinder? A square and cube? Look in your pantry for examples of each, and ask your child to articulate the differences between them. Then, use poster paper to help your child draw and label each example. As a bonus activity, look for additional three-dimensional shapes, like cones, spheres, and triangular prisms, or research how to fold paper into various three-dimensional shapes.
