Remember we have the wonderful collection of **Advent Calendars** to use in the run up to Christmas. I was amused at a comment from Plus Magazine regarding the inclusion of cute kittens wherever possible! Behind Door 1 of their **2019 advent calendar** you will find the story of a rather important cat: Schrödinger’s cat!

Some further additions to the **Christmas 2019 collection**…

From the ATM for younger children, **Midwinter Mathematics** is a downloadable collection of mathematical activities, problem-solving and investigations that are suitable for the winter term for Primary Classrooms. Check ‘Look Inside’ for two free activities, Christmas Stockings where children can think about **systematic listing strategies** by working out the number of arrangements of Christmas Stockings and Paper Chains, a practical task where children use a piece of A4 paper to make the longest paper chain they can.

On the subject of paper chains, with a twist on the relay idea this TES resource, **Chrismas Paper Chains**, has students racing to make the longest Christmas paper chain.

Available from STEM Learning, **Winter Mathematics** from the Shropshire Centre for Mathematics education consists of twenty eight winter-themed activities for younger students (ages 5-11). The collection consists of a variety of investigations, puzzles and games covering many aspects of mathematics.

Also available on STEM Learning, see **Christmas Puzzles**; The National Centre for Excellence in the Teaching of Mathematics (NCETM) published four seasonal puzzles from Amusements in Mathematics by Henry Ernest Dudeney, published in 1917, in their Secondary magazine. I have mentioned Henry Ernest Dudeney’s – **Amusements in Mathematics **before (see **Free Books**), the Kindle edition is free. Several categories of puzzles are available. A search on Christmas returned 23 puzzles, solutions are all provided.

I often mention the Perton Maths Department, check **#PertonChristmaths** for their seasonal Challenge collection.

MEI’s **November / December 2017 M4 Magazine** has been mentioned in the **2019 collection** ( an excellent collection of 10 puzzles and challenges for your students with full teacher notes and solutions). Additionally, we have **MEI’s November Primary Newsletter** which includes some fun festive puzzles for Primary students.

For your A level students, Tom Bennison has a brilliant resource – **Christmas Calculated Colouring**.

Sign up to the **IMA e16plus Newsletter** which is aimed at 16 – 19 year olds who are interested in mathematics and check the latest edition which includes two competitions to enter over the Christmas break as well as various Christmas puzzles and articles.
