Over the years, mathematics has assumed a vital part of the educational landscape of every society. Nevertheless, the subject has attracted considerable attention from researchers relating to the observed low performance and suitable approaches to improve outcomes. In this study, a quasi-experimental design was adopted to establish the effect of the Math-Island on primary school students mathematical motivation and interest. A total of eighty-two students with an age range of 7 – 12 years and a mean age of (M=9.12), (SD= 1.22) participated in the study. The samples were grouped into two and were exposed to a pre-test and post-test investigation. Mean and standard deviation scores were used. The independent t-test analysis established a statistically significant difference between the groups, MD = 11.53, t (80) = 6.313, p < 0.05. Thus, the result supported the studys hypothesis. It was concluded that Math-Island is effective in enhancing students mathematics motivation and interest. The study recommends adopting the system in math class and that teachers be regularly trained on using the device for teaching.
