Computational and Algorithmic Thinking (CAT) is a great way to introduce students to algorithmic thinking, which is a branch of mathematics that involves developing a procedure or formula to solve a problem. CAT problems are designed to be quick to solve and encourage students to develop informal algorithms and apply them to test data of increasing size or complexity.
Choose a paper form a particular year and division. Each paper includes six multiple-choice questions that are relatively easy to solve, followed by nine more challenging problems and also comes with an answer key but not fully worked solutions. There are four divisions available: Upper Primary, Junior, Intermediate and Senior.
Practising on past competition problems is an ideal activity for mathematics classes or individual students, to train for CAT or explore algorithmic thinking.
