Mathematics and numeracy are valuable cognitive learning areas that need to be addressed during the early childhood years. The purpose of this study was to examine the effectiveness of an intervention strategy comprised of creating opportunities, prompting, providing consequences, and prompt fading when teaching preschool children with disabilities numeracy/math skills in the context of identified classroom activities. A single subject multiple-baseline probe design within participants, replicated across three participants, was used to explore the effects of the intervention. The results of this study support the use of the strategy within inclusive preschool settings.
