RTI in Math: Practical Guidelines for Elementary Teachers addresses a growing demand for implementation of response to intervention (RTI) procedures in mathematics education. RTI is used to ensure a successful learning experience for all students by targeting specific areas where students struggle and eliminating threats to learning and development. Drawing upon years of experience in mathematics education and RTI, the authors provide a detailed map of the RTI process, beginning with an overview of RTI research, general procedures, and its potential for application in mathematics. They analyze common student difficulties in both early and upper-elementary math, from basic number sense to complex problem-solving skills, and they apply a three-tier RTI model to the general education classroom. This resource offers guidance through each stage of the RTI process, extensive tools for teacher reflection and growth, and discussion of support strategies beyond the classroom. It also includes a variety of assessment materials, research-based instructional strategies, and numerous case-studies of RTI implementation.
