             The research aims to identify the impact of the place mat strategy on developing high-ranking thinking among the fifth grade primary students. The researcher used 40 students as the sample of the study, 20 for the experimental and 20 for the control group. design with two experimental and control groups. It was confirmed that the two research groups were equal in a number of variables (the chronological age, the level of education for parents and mothers, the results of the pre-test for high-ranking thinking).To achieve the objectives of the research, the researcher prepared a test to measure high-ranking thinking, after reviewing the previous literature in this field. The validity of the tool was also confirmed by using virtual honesty by presenting the test to a group of experts with specialization, and it was agreed on the items of the tool after taking the opinions of the experts. The test items consisted of (28) items using the correction key (zero - one), and applied to A reconnaissance sample to identify the time taken for application. The reliability of the tool was also verified using the Corder-Richardson equation - 20 because it deals with two degrees (zero - one). The stability value reached (0.831), which is a good stability coefficient. After processing the data statistically, the research results showed the following: -There is a statistically significant difference at the level of significance (0.05) in the scores of the high-rank thinking test of the experimental group that was studied according to the place mat strategy and for the pre and posttests, in favor of the post test.There is no statistically significant difference at the level of significance (0.05) in the scores of the high-ranking thinking test of the control group that was studied according to the usual method and for the pre and posttests.There is a statistically significant difference at the level of significance (0.05) between the mean scores of the experimental and control groups in the post-test of high-ranking thinking in favor of the experimental group.        In the light of the results, the researcher presented a set of recommendations and suggestions including the need to use the place mat strategy in the primary stage, especially the finished and pre-finished classes to develop high-ranking thinking skills, and identifying the effect of the place mat on the creative thinking of the fifth grade primary school students.
