Begin by having students form a large circle. Read the first statement, then give students five to ten seconds of think time. Ask students to move to the center of the circle if they agree with the statement and stay on the outside if they disagree. Match students up 1:2, 1:3, 1:4, 1:5, or whatever the proportion of agree/disagree indicates and give them a few minutes to defend their ideas in small groups. Call time, read the statement again, and have students reposition themselves according to whether their ideas have changed or stayed the same. Students who agree with the statement move to the inside of the circle. Students who disagree stay on the outside. Note any changes and then have students go back to the circle for another round. When finished with all rounds, the next step depends on the stage of instruction. If the FACT was used to activate and elicit student thinking, then the next step is to plan and provide lessons that will help students to explore their ideas further and formulate understandings. If the FACT was used during concept development stage provide an opportunity for a whole-class discussion to resolve conceptual conflicts, formalize development of the key ideas, and solidify understanding.
