New resources have been added to the **Christmas Mathematics Resources** and **Mathematical Advent Calendar** pages.

See also some other **updates** including guidance on advance information for Summer 2022 examinations.

From Matthew Scroggs – try his **Advent Calendar for 2021**; behind each day (except Christmas Day), there is a puzzle with a three-digit answer, solve the puzzles to help Santa have a successful test flight so that he can deliver presents; you can read all the details in his post.

Also from Matthew, look at his great Christmas cards, I have made several of these for students. The **2021 Chalkdust card** contains 14 puzzles and can be used interactively or you can download a pdf version. See also the cards from **2020**, **2019**, **2018**, and **2017**.

**Perton Maths Department** continues to provide us with Christmas challenges.

MEI has been sharing Christmas activities, see **#MEIChristmas**. I do like **Building 3D Fractals** from Think Maths.

From STEM Learning, we have **Christmas – 21**, a collection of Christmas-themed resources for STEM subjects including Maths.

One of the STEM resources is **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.

Try this logic puzzle from Sarah Carter – **Reindeer Logic Puzzle** and note her collection of **Christmas resources**.
