The purpose of this research is to determine the academic achievement arising from the Khan Academy ́s Elementary Mathematics course perfomence. The research design was pre-experimental, with pre-observation and post-observation practices. The sample was census, formed by 70 normal school students. Mathematical academic school grades were comparedbefore and after the mediation; as well as the student self-assessment achieved by a reliable question guide (Cronbach's alpha = 0.809). The results show that the course contributes significantly to the increment ofstudents mathema cal skills:school grades raised from X = 7.68 to X = 8.63 (t = -9.03, df = 69, valor crítico de t dos colas= 1.99 p=2.28-13) and self- assesment from X = 7.75 to X 8.75 (t = -9.06, df = 69, valor crítico de t dos colas= 1.99 p=2.65-13). The students got 83.69 (+9.28) basic math skills, they considered that the course assist to increases their peformence in a 4.11 (+0.83), on Likert ́s scale; becasues it enables to remember basic knowledge.
