Puzzle of the Week is a free international puzzle competition for schools. Though aimed at 11-16 year olds, anyone from a registered school can enter. The competition is very simple to run. Puzzles are published weekly on Mondays. School and student performances are recorded and leaderboards are published on the results page.
The Puzzle Library is a brilliant collection; all the previous puzzles are available with detailed answers including extensions and background information. The library is helpfully indexed by topic.
Not a conventional competition, but to challenge your able mathematicians, try Parallel from Simon Singh. All materials and resources are completely free and teachers will have access to all the student scores from the Parallelograms which are automatically marked.
Students do earn points depending on their percentage score on each Parallelogram, which in turn earns mathematical badges. There will be prizes for schools and students linked to the badges in future. Keep an eye on Parallel for the latest news.
Nrich publish problems regularly for which students can submit solutions; problems remain live for about 6 weeks. Nrich are inviting students to send solutions and will publish a selection of them, along with the name of each student and their school.
