Share in the festive spirit with our annual NRICH and Plus mathematical Advent calendars!

NRICH has published two online Advent calendars, one for primary students (ages 5 to 11) and one for secondary (age 11 to 18). Both are filled with 24 of our favourite short problems, one for every day in the run up to Christmas.

The holidays are a time for friends and family, so for the grown-ups, this year's Plus Advent calendar presents an assortment of our favourite Plus articles from our collaboration with the Isaac Newton Institute, our neighbour here in Cambridge, exploring the diversity and excitement of mathematical research. Curl up with with your mince pies and mulled wine and start reading!
