MG 24 – FLAT SURFACES ON THREE-DIMENSIONAL OBJECTS

Children distinguish between three-dimensional objects and two-dimensional shapes.
They identify the 3 dimensions on three-dimensional objects are up and down, left to right, and front to back.
They identify two-dimensional shapes have only 2 of these.
They identify that the flat surfaces of three-dimensional objects are two-dimensional shapes.
They identify that straight lines that meet at vertices are sides, while curved lines are just curved lines.
They identify flat surfaces with sides are faces, while flat surfaces with curved lines are just flat surfaces.
