Providing math tasks with high cognitive demand conveys high expectations for all students by challenging them to engage in higher-order thinking. When students work with these complex or ill-structured problems, they explore and make conceptual connections and can practice Algebraic Thinking, Geometric Reasoning, and Statistical Reasoning.

Watch how this seventh grade teacher uses cognitively demanding tasks to explore Proportional Reasoning. As students work in pairs and approach these tasks in different ways, they practice their Math Communication and critique each others' arguments.
