"Now we can ask why! Beyond Invert & Multiply is a centerpiece for our district’s fraction instruction and professional development. It is the perfect blend of content and pedagogy complemented by meaningful video clips. It is hard to imagine a classroom, school, or district that won’t benefit from such an exceptional resource."
—John SanGiovanni, elementary mathematics instructional facilitator, Howard County Public School System, Howard County, Maryland
"Operations with fractions—a thorny topic in elementary mathematics to teach and to learn—is thoroughly demystified in Beyond Invert & Multiply. I’ve used the videos in professional development sessions; they are indispensable to show how you can present a problem to students and have them respond, knowing that misconceptions will arise."
—Josh Rosen, math specialist, Dobbs Ferry, New York
"The bite-sized chapters in Beyond Invert & Multiply provide just the right amount of detail to allow busy practitioners access to big ideas. The activities are engaging and include clips of real classrooms using the tasks so that readers can see them in action!"
—Nicole Garcia, Mathematics Research and Design Specialist, TeachingWorks, University of Michigan
