A1 مهدي، عبد الله عباس. A2 العليي، يحيى يحيى مظفر AB The study aimed to investigate the effect of using the multiple representations in the achievement of the fourth grade students in the normal and decimal fractions, and their orientation toward mathematics. The sample of the study consisted of (82) school girl from the primary fourth grade in Hajjah city; divided into two groups. One group is the experimental consisted of (39) school girl from Huzaifa Bin Al-Yaman, and the other group is the control one consisted of (43) school girl from Omar Bin Abdul Azeez School. The students were distributed in these groups randomly. The learning and teaching activities were formulated according to the inputs of the multiple representations, and the teacher's instruction-guidebook was designed for this purpose. The experimental group was taught using the multiple representations, whereas the control group was taught using the normal method. The data was collected by using two tests. The first test was achievement test prepared for this purpose which was characterized by reliability and consistency. Its reliability was approved through the specification table and the approval of some referees; whereas its consistency was calculated by using alpha Cronbach formula which was (0.87). The second test was a test of tendency toward mathematics prepared by the researchers. Its structural reliability was confirmed through the scale internal consistency. In addition to its content reliability which was refereed, and its consistency calculated by alpha Cronbach formula which was (0.87). The data were processed by using the (t-test) and the associated- variance analysis. The study found that using the multiple representations in teaching the normal and decimal fractions has an effective impact in the students' achievements and their orientations toward mathematics.
