Hi everyone,

I've put together a set of 100 Python and 100 C# programming challenges for use in the classroom, completely free to download at www.codebash.co.uk/resources

Each challenge includes a problem statement, example I/O, differentiated hints, a mark scheme, and an extension task. Challenges are organised across four tiers - Foundation through to Stretch (A-Level standard) - so they work across Key Stage 3, 4, and into sixth form.

Teacher solutions packs are also available (multiple approaches per challenge, including both built-in and manual implementations).

No email required for the C# packs or the sample downloads. The full Python pack asks for your email so I can share the solutions link separately.

Hope it's useful - feedback welcome.

I have attached the 20 task sample packs to this post so you can check them out first.

Enjoy!
