I like an active classroom where everyone is busy. If you stop in one day it will look like chaos, but it is a carefully orchestrated chaos that cleverly disguises all the learning that we are doing. I use a lot of activities -- and keep the kids moving. Research says that if anyone sits for more than 15 minutes, their brain disengages and learning is not happening. So I design a lot of activities to get kids moving, talking, thinking and participating.
