Any tips on lining up 2.9, 3, and 4yr olds together? Some of them cry when they aren't line leader, push each other, start jumping around like Jumping Beans, copying bad behavior, turn the other direction, ask nonsense questions, etc. (There are roughly 7-10 kids in a group). This line up chaos happens after a short group math lesson of 15 minutes when they are to line up for bathroom break right before snack. Then as they are finished using the bathroom they line up again to walk over to the snack area with more of the same problems. What do you do?
