The Computational and Algorithmic Thinking (CAT) competition gives students the opportunity to develop their problem-solving skills through algorithmic thinking. The competition incorporates unique ‘three-stage tasks’ that encourage students to develop informal algorithms and apply them to test data of increasing size or complexity.

CAT is suitable for any maths class and requires no programming experience. It can be used to develop students’ interest and potential in computer programming.

Like all our competitions, the CAT contains unique problems designed each year by leading educators, academics and industry experts to challenge and extend your students’ problem-solving skills.
