Here is a great way to group your students. You put the kids who you do not want to be together on the smaller circle and the other students go on the bottom. Its a great way to group your students. Just spin the wheel!
Pikme- app that automatically pick students and groups. Can rate responses (or where students are on the LG scale?) using stars. Automatically chooses next student to answer question. Can attach pics with student names too. Cool!
