Freedom and Constraints

Mathematicians often explore structures, notice patterns, find rules and make generalisations. Once they feel they understand a structure, they then push at the boundaries, change the problem, and explore the new structures that emerge.

In this feature, we have chosen some resources from the Freedom and Constraints pathway on wild.maths.org.

Here's how you can send your solutions to these problems.
