From best-selling authors Cheryl Tobey and Carolyn Arline, this book helps pinpoint and reverse students’ common math difficulties. Included are 20 research-based assessment probes designed specifically for Grades 3-5, to help teachers learn to ask the right questions to uncover just where students get confused, and apply practical strategies to get them quickly back on track.

Organized by strand, the probes will enable readers to:

• Quickly and objectively identify and correct students’ difficulties


• Systematically address conceptual misunderstandings and procedural mistakes-- before they become long-term problems


• Plan targeted instruction and remediation in multiplication and division, problem solving, the four operations, factorization, and beyond


• Master the essential CCSM mathematical processes and proficiencies for Grades 3-5

With the help of sample student responses, extensive Teacher Notes, reproducibles, and research-based tips and resources, teachers can quickly eliminate the guesswork and join thousands of busy teachers who’ve used these easy-to-implement probes to foster solid math proficiency!
