Agreement Circles provide a kinesthetic way to activate thinking and engage students in scientific argumentation. Students stand in a circle as the teacher reads a statement. The students who agree with the statement step to the center of the circle. They face their peers still standing in the circle and then match themselves up in small groups of students who agree and disagree. The small groups engage in discussion to defend their thinking. After discussions, the students are given an opportunity to reposition themselves with those who now agree standing in the center of the circle and those who disagree standing on the outer regions of the circle. This is repeated with several rounds of statements relating to the same topic, each time with students starting by standing along the circumference of a large circle.
