This document describes a thinking routine called "Circle of Viewpoints" that is intended to help students explore diverse perspectives on a topic. The routine involves brainstorming different viewpoints, assigning each student a viewpoint, and having them present their viewpoint to the class while embodying that perspective. This encourages students to consider different possibilities rather than just the first technique they find. The author plans to use this routine to have students in a group share different strategies for separating a mixture of sand and sea water, considering various possibilities to decide on the best approach.
