One of the most fundamental math skills for students to learn is basic computational skills. Students who have difficulty learning math skills may benefit from representational approaches, such as TouchMath. A multiprobe, multiple baseline, across-participants design was used in this study to investigate the use of TouchMath with students with physical disabilities. The study was designed to determine the effectiveness of this strategy on the students' ability to solve basic addition problems with sums to 20. All students were successful in reaching the criterion, with high percentages of correct responses using the TouchMath strategy to answer simple addition problems. Data were analyzed by graphic visual analysis and calculation of the percentage of nonoverlapping data. Generalization and maintenance data supported the effectiveness of this strategy.
