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.
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.
Exams and Assessments 2022 – the exam boards have published guidance on advance information that will be provided for summer 2022 exams.
