This study aimed to know the level of Geometric thinking and their relationship to the visual-spatial working memory and academic achievement for first year secondary students. To achieve the goal of the study, the two researchers used the geometric thinking test by Van Hiele after its codification, and the preparation of the visual-spatial working memory test, and the selection of the research sample represented in (65) students from the first year of secondary students, and the study tools were applied to the sample. The results of the study resulted in the existence of a positive correlation relationship with statistical significance between the first-year secondary students degrees on the geometric thinking test and their degrees on the visual-spatial working memory test, and the existence of a positive correlation relationship with statistically significant between the first-year secondary students on the geometric thinking test and their degrees in academic achievement, and the existence of a positive correlation relationship with statistical significance between the first-year secondary students degrees on the visual-spatial working memory test and their degrees in academic achievement. Academic achievement through geometric thinking and visual-spatial working memory was predicted. The study presented a number of recommendations and suggested researches. (Published abstract)
