This is an instructional on how to create mathy Christmas ornaments. If you're looking for something academic or math-related or even just let loose artsy to do for Christmas, this is a wonderful go-to activity! Create tetrahedrons (four sided pyramids) as ornaments. (instructions included on how to expand and make larger ornaments, although tetrahedrons are about the size of a traditional ornament)
Fun activity for when you need a "down" day around the holidays, or want a fun geometry lesson.
Instructions include simple modifications for younger classrooms. (Like don't let them handle scissors or hot glue).
