This book uses RPM techniques to teach mathematical concepts to students. Mathematical concepts are separated from computational details in this book because many students with autism may not have the visual stamina to look at the details of math problems or the performance tolerance ... to complete multi-step problems. The lesson plans in this book include steps that are easy to follow. Mathematics is not just for mathematicians or to complete a competence test. It is an integral part in our daily lives and understanding the concepts will widen the thinking areas of an autistic individual.
