Learning to be systematic

When you are working on a problem, do you approach it in a random and chaotic manner, or do you have a system to make sure you don't miss anything? This collection of problems has been chosen to demonstrate the power of a systematic approach, and we hope that as you work on the tasks you will take the time to develop efficient strategies for getting to a solution and recording what you have done.

Sticky Numbers and 1 Step, 2 Step 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 M, M and M and Counting Factors, and send us your solutions!
