How Many Perimeters is an argumentative task designed for third graders that utilizes visual thinking, hands-on interaction, and divergent thinking, with modifications provided. Students are asked to use algebra tiles to determine if all shapes created with the same three tiles will have the same perimeter. Argumentative language, such as constructing a claim and providing evidence, are heavily used throughout the bulleted and multi-part task, and students are asked to work in teams and share their claims with the class.
