For example...This year, I let the students choose their own seats. It was fun to see them make this decision and it was less work for me. I also have a better idea which students should be kept separated...hee, hee.
As you can see, I arrange my students in teams. Each team has 4 members. Once I finish my diagnostics, I level my students. Then I put 1 high, 1 low, 1 high-average and 1 low-average ability students in each team. Well, that's the plan anyway. As you know, not all classes fit that profile. By dividing the students in this manner I can easily select high-low partners or similar ability partners.
