đ CSUKâs 2025 Advent Coding Challenges Are Here!
A fresh festive season of daily coding fun for your classroom
As December approaches, weâre excited once again to bring a bit of festive magic to Computer Science classrooms across the country. The CSUK Advent Coding Challenges 2025 are ready to launch on December 1st, offering teachers a simple, fun, and engaging way to keep students motivated during the final stretch of term.
Following the success of last yearâs advent calendar, weâve prepared a brand-new set of 19Â bite-sized coding challenges, each designed to be accessible, classroom-friendly, and enjoyable for students of all abilities.
đ Whatâs in this yearâs Advent Calendar?
This yearâs challenges continue our mission to make coding approachable, festive, and fun.
Each daily door reveals a short, purposeful puzzleâperfect as:
-
Lesson starters or plenaries
-
Quick-fire tasks during December lessons
-
Optional festive homework activities
-
Challenges for early finishers
-
Confidence boosters for less experienced coders
Every activity is designed to support core programming thinking in a low-pressure, seasonal context.
đ Designed for All Abilities
The 2025 challenges remain straightforward and accessible, making them ideal for mixed-ability KS3 and KS4 groups. Students donât need advanced Python knowledge to take partâjust curiosity and a willingness to try.
đ Why teachers love the Advent Coding Challenges
Teachers tell us each year that the advent calendar:
-
Brings a fun, positive energy into winter lessons
-
Encourages students to practise problem-solving daily
-
Helps build confidence with manageable, festive tasks
-
Requires minimal preparationâsimply open the dayâs challenge and go
Plus, itâs a great way to keep momentum going at a time of year when motivation often dips.
đ Make December a Coding Celebration
Whether you're using the challenges as mini tasks in lessons, running a form-time coding countdown, or encouraging students to explore them independently, we hope this yearâs advent calendar brings a festive spark to your teaching throughout December.
