Use these teaching tips to help children draw 2-D shapes, recognize shapes in different orientations, identify basic shapes within a larger more complex shape, combine shapes to form larger and different shapes; differentiate between 2-D and 3-D shapes, and name and describe the attributes of 2-D and 3-D shapes. Together with a collection of fun games and activities featuring PBS KIDS characters from Peg and Cat, these resources make elementary math more fun within and outside of the classroom!
