The eight Common Core Standards for Mathematical Practice require students to think critically as they apply their skills and knowledge to mathematical situations. This online course will introduce teachers to specific strategies for engaging students in meaningful problem solving using rich mathematical tasks. Rich tasks present students with the opportunity to conjecture and reason, explore and model, and collaborate and communicate about mathematical thinking. Teachers will explore the rationale for developing a math-task culture as well as develop strategies for selecting, planning, and implementing tasks in the classroom. This course may be completed with or without students.
