Developing Systematic Approaches
Mathematicians like to work systematically on a problem rather than approaching it in a random, unstructured way. The tasks in this feature are designed to provoke students to solve them in a systematic manner.

Age 11 to 14
Challenge Level
This problem is inaccessible without looking at simpler cases, and thus helps students to see the value of specialising in order to generalise.
Shady Symmetry Age 11 to 14Challenge Level
Age 11 to 14
Challenge Level
This problem is a good activity for the visualisation of symmetry, and for encouraging students to work systematically.
Sorted Age 14 to 18Challenge Level
Age 14 to 18
Challenge Level
This problem uses playing cards and video to introduce students to some well-known sorting algorithms.
Odds and Evens Made Fair Age 14 to 16Challenge Level
Age 14 to 16
Challenge Level
To search for a fair game in this probability task, students will need to work systematically and record their findings appropriately.
