Learning to Generalise

When working on maths problems, it's often a good idea to start by trying out some examples using small numbers, and looking for patterns, before looking for general rules. In this set of tasks, we invite you to move from particular cases to generalisations, and use the power of algebra to prove your findings.

Multiple Surprises and Square Number Surprises include solutions that have previously been submitted to NRICH, so you may wish to try these problems first and then compare your approach with the published ones. Then try Tilted Squares and Difference of Two Squares, and send us your solutions!
