The present study was designed to see if children with learning disabilities could be taught three-row, double-digit addition problems using a dot-notation method. Three children with learning disabilities were selected for the study. Prior to the intervention, these students used a combination of count-all and count-on strategies when solving addition problems and used concrete referents such as fingers or tallies. A multiple-probe design was used to evaluate the effectiveness of the intervention with the 3 subjects. The experiment consisted of a teaching phase where students were taught to touch and 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. The final stage consisted of three-row, double-digit addition problems requiring regrouping with touch points removed. Results indicate that the 3 subjects were able to learn and apply the dot-notation method successfully and were able to retain the method from one and a half to four and a half months after completing instruction. Suggestions for future research and for teachers are discussed.
