How do you make sure that you only have, say, 3-4 groups at any given time? So that it doesn't get completely out of hand management-wise for the teacher, it seems that you need 3-4 groups in which the kids are completing the same sorts. If this is the case, how do you just place them on the continuum? I think maybe I'm being a little dense here...so any clarification anyone offers is helpful, whether it seems so or not!!!
