After teaching a reading or math mini-lesson to the whole-group of students, do a 'fist-to-five' it. Students showing a four or five means they understand and are ready to practice on their own. A three means they kind-of understand it but would like a peer to reexplain it to them. If they show a one or two, they remain with the teacher for small-group reteaching. Mrs. Connie Hunt said she did this almost every day and it made a remarkable difference in her students' achievement.
