December…it’s that time of year again…!

And so to the annual update on Mathematical Advent Calendars. We can start this year with a new Advent Calendar resource; checking the **new resources from Teachit Maths**, note the **Interactive advent calendar**. Teachit Maths have made this a free sample resource available to everybody. (Remember that the **free subscription** on this excellent site includes hundreds of high-quality pdf resources.) Teachit Maths describe the resource as an advent calendar in the form of a presentation focusing mainly on mathematics. Suitable for KS3/4. (KS3/4 is UK age 11-16). For each day you will reveal a festive fact, joke, teaching idea, activity or game.

From **Andy Lutwyche** we have his **Christmas Advent Calendar** which covers lots of different topics in number, algebra, shape & space and data and gets progressively more difficult as you go on.

Also from Andy, try his **Advent Calendar – Solving Linear Equations**. Students answer the questions (the solutions are 1 to 24) and each answer links to a word; when the words are put in numerical order an entire joke is revealed! And another…for older students, **Differentiation Advent Calendar** where students are asked to find the gradient of a curve at a given point. Cheesy joke included!

Also on TES you can find an excellent **calendar from Mark Dawes**.

This is a lovely resource with over 30 problem-solving tasks for use in maths lessons in December. Suitable for starter activities, they span a range of abilities in KS3 and KS4. As well as the calendar the resource includes worksheets for some of the problems and an Excel file showing the difficulty of the tasks.

I do like Mark’s suggestions for use in class, he has given instructions for manipulating the resource so teachers can choose the problem they want for any day!

For a collection of starters aimed at KS3 students try this **Christmas Maths Advent Starter Calendar**. This provides a nice mix of activities.

J Calderwood has provided **three Advent Calendars** – Advanced Higher, HIgher and N5 Maths for Scottish Students. A great revision resource which could be adapted for different courses.

From a favourite site, where you can find so many excellent resources, Transum has an **Advent Calendar**. Behind each door, you will find a Christmaths activity, laugh at a cracker joke and solve a mathematical word puzzle.

(See **this post** for more on Transum.)

Try this **Mathsvent Calendar** from **Phil Bruce****. **For December 1st (Saturday – so I think Friday would be a good day to start on the Advent Calendars!) put the baubles in size order along the tinsel starting with the smallest at the bottom.

Very usefully, you can find all 24 **puzzles listed by topic**. These puzzles are great, extensions are given for many of the problems too.

Nrich has published their annual Advent Calendars – one for **Primary** and one for **Secondary**. Secondary students and teachers are encouraged to print off **dotty grids and circle templates** to help with this year’s advent challenges. The Primary advent calendar focusses on activities and games using Dice.

Both Nrich and Plus Magazine have published wonderful collections of Advent resources, clearly, for an Advent Calendar, the year does not matter so we have lots of choices!

From Nrich in 2017 we have a calendar for **Primary** and one for **Secondary** each containing twenty-four problem-solving activities, one for each day in the run-up to Christmas. The secondary tasks come from the excellent **Short Problems** collection. (I will update this post with any new Advent resources from Nrich).

You can, in fact, find a **whole collection of advent calendars on Nrich** and as already mentioned, the year doesn’t matter! Note the different themes available – a **Sudoku** for each day perhaps? Or a **tangram**? Maybe you want to **play a game?**

From **Plus Magazine**, the **Plus 2018 Advent Calendar** features favourite *Plus* podcasts; to quote Plus:

“From the secrets of the Universe to the maths of football stadiums, there should be something there for everyone.”

Like Nrich, you can find a whole collection of **Advent Calendar resources from Plus Magazine**. The **2017 Advent Calendar, **for example, brings you some of their favourite *Plus* videos.

Alternatively how about a **Christmas Revision Calendar** from Access Maths? Scroll right down this **collection of very helpful GCSE Revision Resources** for two Christmas Calendars, one for Foundation and one for Higher.

We should celebrate the women in STEM subjects, try these **Advent Calendar** posts.

Did you know that Maria Gaetana Agnesi was the first woman to write a Maths textbook?

(Thank you **@MEIMaths** for sharing this.)

Alex Pett created his advent calendar complete with history and problems for each day. Alex has provided a **pdf version** or use as a **Google document**.
