If you were to visit a CPM classroom, you would see the teacher doing more than standing in front of the class, telling students what they should know. After reading the objectives of what will be learned that day, the students would be asked to begin the lesson by connecting to what they already know. As the students interact with the others in their team, the teacher circulates throughout the classroom. During this time, the teacher listens to the discussions in the teams, asks clarifying questions and ensures that everyone is on task. If there seems to be class confusion about a problem, the teacher may stop the class and spend a few minutes clarifying. Near the end of class there may be brief student presentations. There will also be a closure activity which will help summarize the activity and may inform the teacher of the depth of student understanding at the end of class.
