An evaluation of the Touch Math method for teaching addition to students with learning disabilities in mathematics

The present study was designed to determine if children with learning disabilities in mathematics could be taught three‐row, double‐digit addition problems using a dot‐notation method. Three children with learning disabilities in mathematics were selected for the study. Prior to the intervention, these students employed a combination of count‐all and count‐on strategies when solving addition problems and relied on concrete referents such as fingers or tallies. A multiple‐probe design was used to evaluate the effectiveness of the intervention. The experiment consisted of a teaching phase where students learned to count the dots on numbers 1 to 9 in a specified pattern, and an intervention phase where students progressed through nine levels of addition problems. Results indicate that the three subjects were able to learn and apply the dot‐notation method successfully, and to retain the method from one‐and‐a‐half to four‐and‐a‐half months after completing instruction.
