High school algebra and geometry teachers use graphing calculators extensively in their classes today. National and state mathematics curriculum standards recommend their use for class work, tests and assignments. Because of recent legislation, including "IDEA 2004" and "No Child Left Behind", most students with mild disabilities are placed in general education classes. Although graphing calculators are clearly useful resources for both teachers and students, the calculators frequently present challenges for students with learning problems. The purposes of this article are to describe the characteristics of students with learning problems that interfere with the use of graphing calculators and then to make recommendations that will help students and teachers have successful experiences in algebra and geometry classes.
