# Working Systematically

Mathematicians try to work systematically so they can see how they worked something out, and see patterns which messy work might not reveal. Scroll down to see our complete collection of lower primary problems that require you to work systematically, or explore the two sub-collections.

### Finding All Possibilities Lower Primary

These activities focus on finding all possible solutions so if you work in a systematic way, you won't leave any out.

### Ordered Ways of Working Lower Primary

These activities lend themselves to systematic working in the sense that it helps if you have an ordered approach.
