Other suggestions for December:

  • This year, Computer Science Education Week runs from 9-15 December, during which time, they are also encouraging everybody, young and old, to engage with their annual Hour of Code event.  Coding is the future! Computers are changing every industry on the planet. Every 21st-century student should have the opportunity to build technology. Click on the links above to access Hour of Code and other computer science activities for learners of all ages. Operation Maths users can also access the tailor-made Operation Maths Scratch lessons on 
  • NRICH have recently launched their 2018 Primary Advent Calendar. They have lots of other Christmas-themed activities that can be accessed here: They also have an Advent-themed sudoku challenge that some of the more-able senior class pupils might like to tackle.
  • Mash-up Maths have a Christmas-themed 12 Days of Holiday Math Challenges. Suitable for 1st class up, it might be better to hide all the puzzle initially. Then, reveal just one line at a time and ask the children to record and justify all the possible solutions based on what they know at that point. As they move through each line, they can then justify why they should now discard certain options. This is a better way to engage all of the children in thinking mathematically, rather than it just becoming a race to the solution (which can often turn-off those less mathematically-inclined). For more of this type of problem sign up to the Mash-up Maths weekly newsletter, to receive lots of other themed maths puzzles and challenges like this Grinch-themed challenge.
  • Interested in more Christmas-themed maths problems? From Dec 1-24 the German Maths Society posts a daily problem (in English) on its online Advent Calendar. There are 3 levels of difficulty, 4th class to adults.
