I NEED HELP WITH CREATING GROUPS! In efforts to increase student achievement, our school wants us to implement more group time in math and reading. They would like these groups to be working during a 30 min. period so that we can target the 2 lowest groups of kids (15 min. each) to reteach. I'm in third grade and honestly not very good with activities to keep the other kids working while I reteach. We are limited on computers, so having internet activities is not really a good option, because there would probably only be 1 computer open for that. I am looking for activities that aren't just "fluff" but would be valuable to my low groups as well as middle and high groups. As always, TIA!
