My classes have always liked Unit 6 the best. I get feedback that it is the most fun and they wish there were more lessons and activities. Once they figured out the last lesson with the wires & LEDs, they especially wanted to work with the wires and LEDs more.
Is there an extension to this unit? Are there lessons in CSF or one of the other curriculums using CB? It went too fast and left my students wanting more opportunities to code for the Circuit Board.
