Published nine times a year, this journal from the National Council of Teachers of Mathematics (NCTM) provides a range of in-depth articles and features including practical lesson ideas, teaching strategies and problems to investigate with students. These features and articles offer an important source of professional development to readers.

Dorothy is again uprooted from her home! In The Mathematics of Oz: Mental Gymnastics From Beyond the Edge, Dorothy must solve an array of brainteasers in order to escape the clutches of her abductors, a group of mathematically obsessed aliens. Each short chapter is a mathematical adventure in which Dorothy is presented with a mystery, a puzzle or a problem to solve. The author rates the problems in terms of difficulty. One does not have to complete all the chapters or complete the chapters se...

Consisting of individual lessons with blackline masters and teacher notes, this resource introduces linear, exponential and quadratic functions encountered in algebra. Each chapter features a graph and a series of statements describing a function that are explored prior to the introduction of tables or algebraic notation. Subsequent chapter lessons introduce coordinates, quantitative graphs and tables. To deepen conceptual understanding of a function, the activities emphasize verbal, numeric,...

This resource considers new ways to assess students, focuses on assessment tasks, offers ways to plan and conduct a classroom assessment program and discusses the scoring, grading, reporting and use of assessment data. The editors provide opportunities for teachers to reflect on their teaching practice and how they use mathematical assessment in the classroom. The book includes a table of contents, a listing of resources and an index.

Written as a guide for parents and educators, this book argues that math should be taught as the highest form of intellectual play rather than as a step-by-step acquisition of skills and facts. The authors emphasize that mathematics is meant to be explored and that it does not require special talent or ability.

This volume and its companion are professional research-based resources that promote a problem-solving approach to mathematics instruction. This approach engages students in making sense of problematic tasks in which mathematical concepts are embedded. The writers address issues and perspectives related to this approach, provide suggestions to select and use appropriate tasks and learning tools and provide examples of the use of this approach in various classroom settings.
