The purpose behind this action research was to determine the effect Spatial-Temporal (ST) Math, a web-based mathematics program, has on student achievement at a second grade level. The ST Math program was given to a small group of second grade students on top of the classroom mathematics curriculum while another group of students strictly used the classroom mathematics curriculum. A pre and post assessment were given to these students over an eight week period. This quantitative data was analyzed to determine the correlation between the students’ exposer to ST Math and their achievement on the assessments. After analyzing the data, it shows that students’ scores who participated in the ST Math program increased. However, when compared to the students who did not participate in the math program, there was no distinct difference in scores.
