Putting Essential Understanding of Ratios and Proportions into Practice in Grades 6 - 8
Members Save up to 30%!
Do your students think they can model ratios with sets of discrete objects and combine them to show the addition of ratios? Do they believe that equivalent ratios are based on additive relationships rather than multiplicative ones?
What tasks can you offer what questions can you ask to determine what your students know or don’t know and move them forward in their thinking?
This book focuses on the specialized pedagogical content knowledge that you need to teach ratios and proportions effectively in grades 6-8. The authors demonstrate how to use this multifaceted knowledge to address the big ideas and essential understandings that students must develop for success with ratios and
proportions--not only in their current work, but also in higher-level mathematics and a myriad of real-world contexts.
Explore rich, research-based strategies and tasks that show how students are reasoning about and making sense of ratios and proportions. Use the opportunities that these and similar tasks provide to build on their understanding while identifying and correcting misunderstandings that may be keeping them from
taking the next steps in learning.
You have essential understanding. It’s time to put it into practice in your teaching.
The Putting Essential Understanding into Practice Series moves NCTM’s Essential Understanding Series into the classroom. The new series details and explores best practices for teaching the essential ideas that students must grasp about fundamental topics in mathematics topics that are challenging to learn and
teach but are critical to the development of mathematical understanding.
Classroom vignettes and samples of student work bring each topic to life, and questions for reader reflection open it up for hands-on exploration. Each volume underscores connections with the Common Core State Standards for Mathematics while highlighting the knowledge of learners, curriculum, instructional
strategies, and assessment that pedagogical content knowledge entails. Resources and tasks are available at nctm.org/more4U.
Maximize the potential of student-centered learning and teaching by putting essential understanding into practice.
