Must Share: Math-y Christmas Ideas

Over the years, I've shared quite a few Christmas ideas in my Monday Must Read posts. This year, I've taken the time to go through these posts and compile these holiday-themed ideas in a single post. Hopefully this will make accessing these amazing ideas that other math teachers have shared on twitter even easier to implement in your own classroom.

I've also written a few holiday themed posts of my own in years past. Be sure to check them out as well. Hopefully all of these ideas will given you plenty of inspiration to keep your students busy during these last few weeks of the semester (or year depending on your hemisphere).

I hope you enjoy reading through these math-y (and a few science related) holiday ideas for your classroom.








 And, now for the amazing ideas from previous Monday Must Read posts.

I first learned to play Nim as a sixth grader in math class. I've always played with physical objects like stones, pencils, popsicle sticks, etc. So, I was super intrigued to see nim played on paper. Thanks to Donna Buckley for the idea! Plus, they look like cute little Christmas trees!
