There has been vast research on the effectiveness of Computer-Assisted Intervention (CAI) in helping autistic students for learning various knowledge and skills. However, most of them are in the areas of literacy and only a small number of them are in numeracy. Hence, this research is aimed to examine a CAI in helping autistic students to learn a concept of addition in mathematics. Three male students diagnosed with autism and with prerequisite skills participated in this research. A pre-post-test design was implemented in the research. Findings of this research are promising in which all three participants demonstrated a positive outcome at the end of the treatment.
