AU - العبيدي، لقاء ضياء عبد اللطيف جاسم AB - The objective of the research was to identify the impact of the differential education strategy in the achievement of mathematics for fifth graders. Therefore, the following hypothesis was developed: There is no statistically significant difference at the level of (0.05) between the average of the students of the experimental group who will study according to the differentiated and average education strategy Classes of students in the control group who will study according to the normal method of mathematics achievement. The researcher selected two divisions from the (Naseer Primary Mixed School), (B), experimental group, and (A) control group, and the sample of students was (60) for each group (30) students and students. After the parity between the two groups tested in: 1) previous information. 2) The age of the time calculated in months. 3) Previous collection in mathematics. The study tool was prepared (the achievement test) and after the acquisition of the coefficient of discrimination and saturation and honesty and stability and the preparation of the teaching plans according to the distinct education strategy of the experimental group and the teaching plans of the control group and after the end of the trial period the researcher provided the test of achievement of the groups and after the calculation of grades was the difference in favor of the experimental group and calculated size The effect was high, indicating the impact of the differential education strategy. The researcher made a number of recommendations and suggestions.
