Origami
Origami is my favorite activity for two days before Christmas vacation. I use directions from Tomoko Fuse's Unit Origami and Origami Boxes. I use colored copy paper that I've cut to 8.5" square. Its heavy weight (compared to origami paper) makes it great for boxes.
I also like to make polyhedra with PHIZZ units.

Math history charts hang all around my room. If you are distracted, there is always something new to learn.
