The study aimed to investigate the effect of using the calculator CASIO fx-991EX on mathematical achievement among the tenth-grade students in Jordan. The study sample consisted (30) students from grade (10), selected from private international schools that follow the American system AHSD. The quasi-experimental design based on experimental and control groups was used in this study, an experimental group of (16) students, who studied using CASIO fx-991EX, and control group of (14) students, who studied using traditional studying method. To achieve the aim of the study, a mathematical achievement test was used for data collection; the validity and reliability of the test were measured and found acceptable for the study purpose. The results showed that there was a significant difference in mathematical achievement among the tenth-grade students in Jordan, in favor of the experimental group who studied using the calculator CASIO fx-991EX. Based on the result, the researcher recommended the adoption of the results of this study as a response for the effect of using calculators on developing mathematical achievement among students.
