This interactive, practical resource gives educators sound knowledge and expertise for successfully implementing RTI in mathematics and addressing the challenges involved. RTI and Mathematics clarifies and describes the issues of RTI, the connections among teachers' knowledge and skills and their use with RTI, and the role of the teacher within the classroom and school, and provides evidence-based content, scenarios, examples, resources, and activities; modeling description; and reflection upon the key learning outcomes of RTI. Included is an illustrative continuous case study of a mathematics teacher as she implements RTI in her classroom, and a myriad of information and resources educators can use immediately within K-8 classrooms in order to implement RTI in mathematics successfully.
