The document discusses differentiated instruction (DI) and provides examples of how to implement anchor activities in the classroom. It defines DI as teaching that accounts for student variance and starts where students are rather than using a one-size-fits-all approach. It then gives examples of anchor activities such as learning packets, activity boxes, and research projects that provide meaningful work for students to do when they finish assignments early or need independent practice. The document provides tips for planning, introducing, and managing anchor activities to create differentiated groups and free up teachers to work with other students.
