I have been wanting to start a "Lunch Bunch" group for a while, but honestly, I just couldn't get past the logistics of who can come, how will they know they get to come, how will the teachers know they have permission to come, and what will we do to make it a meaningful learning experience. Usually when I start a small group, it has a focus topic and specific students are selected to attend based on their needs. Then I can notify teachers that this small group occurs weekly and to expect a pass each week on that day.
But what I want to create is an always revolving group that meets during recess and the only "need" is the need to be a part of a Group. I even had 5th graders suggesting that I start a group like this, so I know the "need" is out there. Thus I am back to my problem of logistics.
