Computational and Algorithmic Thinking Competition

The Computational and Algorithmic Thinking (CAT) competition is a one-hour problem solving competition designed to encourage student curiosity and promote multiple modes of thinking. Both teachers and students do not necessarily require previous computer programming ability, but the competition will help identify students’ computer programming potential—something that they might not normally have the opportunity to demonstrate.

The competition is an ideal activity to encourage students to solve real-world problems. It is suitable for any mathematics class and the process helps students become more confident as they take on interesting new challenges. This competition has a mixture of multiple-choice and integer answers and incorporates unique ‘three-stage tasks’ that encourage students to develop informal algorithms and apply them to test data of increasing size or complexity. The original problems are designed to be quick to solve and highly approachable, and range in difficulty from very easy to challenging. Some questions test the ability to perform procedures, others require logical thought, while the more challenging problems require the identification and application of algorithms.

The CAT has four divisions: Upper Primary (years 5-6), Junior (years 7-8), Intermediate (years 9-10) and Senior (years 11-12).

CAT will be held on Wednesday 29 April 2020
