  The present Search aims to identify the impact of  numbered heads Strategy in development of  Mathematical thinking For 4th graders in mathematics . The Search  sample was Intentionally chosen From the research community , and consist from (60) pupils From 4th graders at Zayed Ibn Thabet school For boys. With (30) pupils in each of two groups The experimental group which studied by the numbered heads Strategy and Control group Which Studied according to normal method. the research tool consist of a mathematical thinking test Consisting From(15) paragraph items in a  multiple – Choice format and then verified its validity and reliability of Cordor – Ritchardson (20) which reached 0.79 .The experiment was applied during the First Semester of the academic year (2022-2023) it When Started on Sunday coincidence (30/10/2022) and ended Thursday Coincidence (29/12/ 2022) and then applied the Mathematic thinking test After wards. And the data was analyzed statistically by using T- test For independent two Samples , the results Showed that there  Statistically Significant difference between two groups in the Mathematic thinking in favor of the  experimental group , in  the light of the Search results the Searcher Submitted numbers of the Recommendation and proposal.
