The centerpiece of these materials is a set of narrative cases drawn from the QUASAR project and viewed through the lens of the Mathematical Tasks Framework - a characterization of how mathematical tasks unfold during classroom instruction. The cases portray the enactment of cognitively challenging tasks in middle grades classrooms. The Framework provides a tool for guiding a discussion of cases and the challenges of using high-level tasks for instruction.
