When teaching history, I used to try to explain this to students- usually with little success. People have a hard time grasping how many people it took to make them. and how that gives us huge family trees. ** This is very interesting.
Get kids to design a modern artists alphabet poster of their own- another idea is their own A-Z of contemporary art (pinched the later idea from art history presenter Andrew Frost). Could use this idea for PC artists, too.
