For this year's 8th grade painting collaboration, I decided to use Gustav Klimt's Tree of Life. Twenty students each chose one of the pieces to paint when they were finished with their other painting assignments. After the pieces were put together, I added a bit of gold in some of the pieces to pay homage to Klimt's use of gold in his work.
