This study aimed at investigating the effect of using the computer as an educational teaching aid in the achievement of the fifth grade students in a unit on Areas , compared with two ways the traditional method with work-sheets, and the method of traditional teaching .

This study fried to answer the following questions:

1- Are there any significant statistical differences at ( α = 0.05 ) in the achievement of the elementary fifth grade students in mathematics between the first controlling group and the experimental group " the computer" .

2- Are there any significant statistical differences at ( α = 0.05 ) in the achievement of the elementary fifth grade students in mathematics between the second controlling group " work sheets " and the experimental group " the computer" .

3- Are there any significant statistical differences at (α = 0.05 ) in the achievement of the elementary fifth grade students due to educational method .

4- Are there any significant statistical differences at (α = 0.05 ) in the achievement of the elementary fifth grade students in mathematics by the use of " computer " due to sex .

To answer all these questions, the sample of study consisted of (86) students from the students of fifth grade from ramalla private schools. Those students were randomly chosen with (3) schools.

Students were distributed into three group two controlling groups and the third experimental. Where mail and female students study in different classes, in two groups, the first controlling and the experimental, while the second controlling group consisted of female only.

In this study an educational programmer prepared by the research was used within the program (Power Point), in which the material was presented as it is in the authorized book for fifth elementary grade. ( 8) lessens out of ( 10 ) in the area unit were explained in average ( 5 ) lessons every week , in real ( 12 ) lessons .

All the group studied the same number of lessons and the same subject.
The results of experimental shows the following:

1- The existence of significant statistical difference at ( α = 0.05 ) in the achievement of the elementary fifth grade students in Mathematics in the first controlling group " the traditional " and second controlling group " work sheets " and experimental group " the computer " the points were in favor of experimental group " the computer " .

2- There are some significant statistical differences at ( α = 0.05 ) in the achievement of the elementary fifth grade students in mathematics by using " the computer " due to sex , and this in favor of females .

Because of the results the researcher found , the researcher advised of looking for especial computer laboratory that helps in the educational process in all subjects , and this can be used to present educational material or helping the Teacher in making any experiment or any educational method during explanation and the research advised in making additional studies on The educational methods in Mathematics and especially using
( Power Point ) as an Educational method in presenting the educational material .
