Self-regulated Strategy Development for Math (SRSDMATH), is a novel approach to solving math problems using research-based methods. The SRSD strategy was developed by Karen Harris to aid in the writing compositions of students with disabilities. It has since been used to teach writing, reading, and math for these same students. The math strategies used in previous research have focused on word problems and vocabulary. SRSDMATH, developed by Ennis and Losinski, builds on this solid foundation to include strategic instruction in the calculation of math problems starting with the addition and subtraction of fractions with reducing and mixed numbers.
