3D shapes offer a different view to the regular shapes your child is used to seeing and drawing by now. For example, a square shape is in 2D, and its 3D form is a cube. A pyramid is in 3D, and its 2D form is a prism. First explain this to your kids; that 3D shapes are the view from another angle, giving the shape depth, height, and width. In this simple worksheet, your child will circle the flat shapes that match the 3D shapes pictured in the printout.
