Objectives: The aim of this study was to examine the effects of cognitive games (games based on executive functioning) on the attention and response inhibition of students with dyscalculia. Method: This study used the pretest-posttest quasi-experimental design with a control group. In this study, 20 students with dyscalculia selected through purposive sampling were randomly divided into control and experimental groups (n=10 each). The experimental group participated in twelve 60-minute sessions of cognitive games for six weeks. The omission error and commission error sub-scales of the Test of Variables of Attention (TOVA) were utilized to evaluate attention and response inhibition performance, respectively. Data were analyzed by MANCOVA. Results: The analysis of the data revealed a significant difference in results between the experimental group and the control group following intervention. Conclusion: Cognitive games improve the attention and response inhibition performance of students with dyscalculia
