The research problem in this study is whether there is an effect of using the coolmath4kids website on the ability of students in the second grade at SD Muhammadiyah Perumnas to calculate quickly. The study used a quantitative approach with a pre-experimental design and a one-group pretest-posttest design. The population in this study is all the students in Year 2 at SD Muhammadiyah Perumnas, with a sample of 23 students selected using the total sampling technique.

Data analysis techniques used statistic descriptive and inferential with the help of SPSS 25. The data normality test was performed using the Shapiro-Wilk test, which showed that the pretest and posttest data were normally distributed. The hypothesis test used was paired sample t-test. The results of the study showed an increase in the average score from 51.13 (pre-test) to 89.35 (post-test). The paired samples t-test showed a significance value of 0.000 < 0.05, meaning that H0 was rejected and H1 was accepted.
