### Math Links for Week Ending Dec. 22nd, 2017

Do you want to know how much garland you need for your conical shaped Christmas tree? How about how to win that Christmas match of Monopoly with your family? Listen to @FryRsquared on @SciFri as she talks about her (and @Mathistopheles ) new book "The Indisputable Existence of Santa Claus (The mathematics of Christmas)". Listen here

We put a new activity on our blog that combines some of the work of @JoBoaler and @FawnpNguyen. Using visual patterns we made these 32 visual pattern cards to give to kids to talk about how the pattern grows. Then they develop the general term and finally I think that when you have all of the different terms you can start to develop some ideas on how to get those general terms more easily.

@MrOrr_Geek has added a new feature to his @MathBeforeBed site. Just enter your email and you will get 20 pages each with two different prompts for your students to show their thinking. The Math Before Bed has great starters for kids of all ages. So check that out too.

I like activities that involve students communicating mathematically to each other. In this activity from @MaryBourassa she has her grade 12 students pairing up. One person picks a graph and has to describe it to their partner. Their partner has to draw it. Get the downloads at the link.

I love this video from @standupmaths for spreading precise Christmas mathematical cheer. These are instructions (and a rant) on how to make a scientifically and mathematically accurate snowflake. There is actually a lot of math here from six fold symmetry to trig and radian measure.
