3D Shapes in art are called Form. My product contains an introduction to form/3d geometric shapes in art. There are four art projects with directions, templates to copy, supply lists, photos of the steps needed to take, and photos of finished products.
These products combine math and art.
The 3-d shapes are the sphere, the cube, and the 3-d rectangle and triangle. The supplies are simple classroom supplies and the lesson are easy to follow.
