I teach 4th grade science and social studies and am struggling a little with student grouping during centers. 1. When I group students by ability level: below, on, and above... my below level students seem to need my support throughout all the centers but I can't follow them around the whole time. I also need to meet with other students and monitor all of my groups. 2. Does anyone mix the ability levels of their groups? My only problem with this is: one of my centers is always a reading center and I try to differentiate the readings and meet with students when they visit this center. How can I support my students when each one of them would be reading something different. Would I split the group up and sit with my lower students and allow the others to work on their own or in partners? 3. I really feel that my original grouping by ability is just not working. I think my lower kids would benefit from the on/above level students assistance. 4. What do you think or do for centers? Thank you!
