The explosion of Accessible Educational Materials (AEM) made possible by technologies, materials and manipulatives creates a UDL pathway to using multiple representations of the same object to meet the needs of varying student populations and learning preferences for different attributes; possibly at the same time. Educators have become aware that they can cross over exceptionalities to use materials, manipulatives, and technologies to meet the needs of general education, special education, gifted, sighted, and visually impaired students, etc. In this resource, a modified version of Jerome Bruner’s mathematical Concrete to Abstract theory is used as a mnemonic device to provide an organizational structure for a variety of science materials. This concrete pictorial abstract (CPA) model can be generalized to other subject areas.
