The researchers dealt with a topic entitled "Differentiated activities; to develop spatial ability, and curiosity; among students with difficulties learning mathematics". They used Descriptive method to It was reviewed from the relevant educational literature - to a list of the dimensions of spatial ability, and it’s skills, and the experimental curriculum with its quasiexperimental design of one group, were counted with measurement: pre and post; to measure the impact of activities based on the principles of differentiated education in developing dimensions of spatial ability and curiosity. The students of the fourth grade of primary school with difficulties learning mathematics, and the research aimed to test the validity of two hypotheses emanating from the first four sub-hypotheses, and the researchers followed a set of procedures to answer the research questions represented in: first: preparing the research tools: 1) is a questionnaire to determine the dimensions of spatial ability and the skills associated with it, 2) is a test of spatial ability for fourth-grade students with difficulties learning mathematics, and 3) is the illustrated curiosity scale for Maw Maw, Second: selection the research sample, and the application of the tools on them, third: the data collection and analysis that resulted from the previous procedures, and one of the most important results of the research is the high level of spatial ability skills among the students of the research sample, where the average scores of the students of the research group came in the dimensional measurement of the spatial ability test as a whole (14.13). Whereas in the pre-measurement it was (5.8), and the value of “t” between the two averages of (26.6) shows that the results came in favor of the post-measurement, and that the effect of the independent variable (discriminatory activities) in the dimensions of the spatial ability test as a whole was large. The value of the Eta square is (0.96) which is greater than (0.15), and therefore there is an effectiveness of the differential activities in developing the "spatial ability" as a whole. With regard to the curiosity scale, it was found that there was a statistically significant difference between the mean scores of the research sample, in the two measurements: pre, and dimensional. This is in favor of the average dimensional measurement; and a set of recommendations and proposed researches that could benefit those in charge of making social studies curricula and math, nationalism.
