Making quarters

In STEM club we were making quarters in multiple different ways. On the left, are the quarters that some of us made. Also, we were having a competition to see who would create the most and one of the teams one with 9 and the other 3 groups with 4 and 4 and 3 and winning team got a chocolate bar each. However, on the right are the ones that were the same and they became rubbish.
