The recent research aims at knowing effect of using Polia strategy in development of students’ skills in solving mathematical problems for 5th grade students in Diyala province in Iraq. The reason for choosing 5th grade because there is one section in it, so the researcher applied his experiment on this section which contains (30) students as conjugated samples, so the researcher did not need equivalence of groups. The researcher made an achievement test for pre – test and applied it on the group, and started to teach the group by himself by using Polia strategy to solve mathematical problem, and prepared scientific subject, formulation of behavioral objectives and teaching plans for this purpose. Research tool was achievement test for students’ skills in mathematical problems solving. Validity and reliability test was made in addition to difficult coefficient and discrimination power for test items. Post test was made after finishing the experiment. After correction and calculation degrees average for both pre and post tests, (t-test) was used to make resuits analysis. Researcher concluded that there is significant statistical differences between average degrees of pre and post test for favor of post test. This means that there is positive role for using Polia strategy in solving mathematical problem. Researcher recommended using this strategy in other stages. (Published abstract)
