So, time to relax and what better way to relax than with a puzzle or two?!

On Nrich you’ll find a collection of advent calendars a **Sudoku** for each day perhaps? (Solutions are supplied if you want them). Or a **tangram**? Maybe you want to **play a game? **(Clearly the year doesn’t matter for an Advent Calendar!)

Plus Magazine also have an **Advent Calendar **where you will find some of their favourite books and other mathematical toys.

For many more games and puzzles, see **this collection **including a challenging logic puzzle from **Coolmath Games – can you set the circuits to light up that Christmas tree?! **If any of you have any little relatives they might enjoy Top Marks’ collection of their favourite **Christmas Activities**.

Perhaps you could make your Mathematical friends some cards! Why not put a Desmos tree on the cover?! Note this is simply a collection of lines and circles, **as you can see from the syntax** it is very easy to restrict x or y values. (For more on getting creative with Desmos, see **Graph Art**).

Staying with the subject of cards you can practise your coding skills with this Scratch project with a **very clear tutorial on how to make a greeting card**; not a great work, but I did enjoy playing with Scratch: **here’s one I made earlier! **If you are feeling creative you might like these **Christmas fonts**.

On the subject of coding and Christmas trees you might enjoy **Holiday Lights **where you can use coding to light up a holiday tree outside The White House. Holiday Lights comes from Google as part of their **Made With Code** initiative. Note that **Google’s Blockly** is being used for the code.

For some rather more advanced coding, there’s a rather nice Christmas tree generator **here**; select Auto Generate and sit back and admire the tree! Note that for any Scratch project you can ‘look inside’ and see the coding – a good way to learn more syntax.
