Choose and Defend! is an activity during which students are asked to choose and defend their position on a statement (true or false) provided in writing by the teacher or another student. Example of a true statement: A square is always a rectangle. Example of a false statement: If a square is a rectangle, then a rectangle is a square.
This activity can be used either at the beginning of the lesson or during a specific part of the lesson with the ultimate goal of revealing and discussing students' thinking and/or misconceptions and promoting students' participation in discourse (oral and written). This activity is also intended to support students' engagement in Common Core Standards for Mathematical practice.
