"The 38 problems and tasks for students in this book are organized into the major areas of the Common Core for grades 3-5: operations and algebraic thinking; number and operations in base ten; fractions; measurements and data; and geometry. For each task, teachers will find a rich, engaging problem or set of problems to use as a lesson starting point, with accompanying discussions that tie the tasks to specific Common Core domains and clusters. Follow-up sections highlight the CCSS Standards for Mathematical Practice students will engage in as they work on these problems."--Back cover.
