Mathematicians often talk about the importance of working systematically. This means that rather than working in a haphazard and random way, there is a methodical, organised and logical approach. The problems below will challenge you to work systematically and will help you appreciate the benefits of working in this way.

Scroll down to see our complete collection of Upper Primary problems, or explore the two sub-collections.

We also have a collection of Lower Primary problems that lend themselves to working systematically.

Primary teachers may like to read our article Encouraging Primary Children to Work Systematically.
