Direct is putting them next to each other and comparing using spatial reasoning/visuals. Indirect comparison requires the use of an outside unit or tool to help measure more discretely (for example the blocks in the popcorn task).
I love the idea of using these comparison tools to introduce circle work in middle school, to help students make conceptual connections before algorithms!
