MCYA Challenge Practice Problems

This page is intended to give a taste of the MCYA Challenge and a chance for students to practise their mathematical problem solving. Problems will cover a wide range of standards, from accessible to all students up to challenging.

When a problem is posted without solution, send your solution here. Clearly indicate your school year and the particular problem you are answering. If your solution is complete we will acknowledge with your name, school and school year. Generally when a sufficient number of correct solutions are in we will post the complete solution, and follow with new problems.
