Materials

You can use white or different colors of paper to print the models.
Students can decorate the 2D Shape (also called a NET), if desired. Then they need to cut, fold, and glue their 2D paper shape to make a 3D Figure.
These Tetrahedrons can be used as colorful holiday ornaments or as decorations any time of year. They can be hung on a tree, in windows, from the ceiling, on a mobile, etc.
