You can download an Octahedron model (NET) from the Math is Fun Website. Click on the link below.
You can use any paper that works in a printer to print the models.
Students can decorate the 2D Shape (NET), if desired. Then they will need to cut, fold, and glue the 2D paper shape to make a 3D Figure.
These 3D Shaped Octahedrons can be used as colorful holiday ornaments or as decorations any time of year. They can be hung in windows, from the ceiling, on a mobile, on a tree, etc.
