### 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!

Check out this Christmas-themed parabola activity from Math with P. Nik.

These triangular Christmas trees from Mark Ekstrom are too awesome not to share.
Mrs. Tangel shows how to use factor trees in a festive manner. Keep this in mind for next Christmas!

Mrs. Allan shares a Christmas gift idea that could also work well as an end-of-year gift for students in your math club.

Here's a lovely real-world math problem for Christmas decorating from Ms. Kulcsar.

Luke shares an awesome prime based Christmas puzzle

Kerri Homan inspires with a math-themed Christmas craft. It's never too early to start thinking about how you will celebrate this year!

I love this Christmas themed mathematics display that James created with his students!

I love these ornaments that Mrs. Yakubov made for all of her students for Christmas.

Here's another display that caught my eye on Twitter from Park Junior School. I would like to extend this project to give students a task to draw Christmas ornaments based on the circumference, area, radius, or diameter.

I love Sarah's project where she challenged her students to come up with a strategy to determine if Zebra Cakes or Christmas Tree Cakes are better. How fun is this?!?

This Elf puzzle from Maths@ KPS looks fun!

Here are some others from KPS Maths that also caught my eye.

Want to join the magic of snowflakes and math (specifically statistics)? Check out this awesomeness from Anna Fergusson. Each snowflake is created from one one of the letters in "happy holidays." Anna even crated a free web app that we can all use to make our own secret statistical snowflakes from a word or phrase of our own choosing!
