I have 20 kids. and I just can't decide if I should put them in four groups of 5 or five groups of 4 for their play center time. Any thoughts?

Forgive the question; I'm a high school math teacher and seldom do this stuff. What's your intention in forming the groups? What sort of work will they do? Will they have to pair off? (groups of 4 obviously the better choice then.) Will they be expected to do many large projects (larger groups make more sense then.) Will each group be doing a different activity? (Do you have enough activities for 5 groups??) It seems to me, at least as an outsider looking in, that you would have to consider the point behind setting up the groups before deciding which would work better.

I think 5 groups of 4. Even if it is just developmental centers, you don't want them to be overcrowed. I'm so sad... this year I will have 24 and 25 in my am/pm classes. SO many little ones

definitely 5 groups of 4. Also, in my district we often pick up an extra kid or two right before school starts so having smaller groups would leave you a little extra room to expand the groups if you need to.

for play center, I never make groups for the kids, I just have choices for them to play ( maybe 10 choices) and then let them choose. I don't let more than 4 kids play in any area, if that is your concern. but I allow them to make their own choice.

I had 5 groups of 6 for two years. That was kind of crazy. Last year I had 5 groups of 4 and it was heaven. My work stations were nice and calm with only 4 at each station.
