الملخص EN

The aim of this research is to identify the statistical thinking skills needed in the content of the second-grade mathematics books, and to identify the extent to which second-grade mathematics books include average of statistical thinking skills.

To achieve the goals, the research used the descriptive analytical method, represented by the method of content analysis, where the content of the mathematics book was analysed the second grade average for the second semester and specifically chapter ninth (statistics), for this was prepared the tool of content analysis, which was built in the light of skills Statistical thinking, which consisted of (23) sub-skill in its final form after ascertaining the sincerity and stability of the tool.

The research found that the average percentage of inclusion of mathematical content in the second-grade mathematics book is an average of statistical thinking skills of (22.4% ) and is considered a low percentage, as the skill of describing the data came first (190) times and by (42.0% ) and at an rate average, followed by skill Collecting, organizing and summarizing data by repeating (99) times and with a rate of (21.9% ) and at an low inclusion rate, and at the third rank among statistical thinking skills comes a skill that represents data graphically (79) times and by (17.4% ) and with a very low inclusion rate, and in the last skill comes data analysis And its interpretation by repeating (38) times and (8.4% ) and with a very low inclusion rate.

One of the most important recommendations of the research is to direct educational experts and those in charge of planning educational curricula towards the importance of enhancing statistical thinking skills among middle school students, and reconsidering the inclusion of statistical thinking skills in mathematics books in the second-grade intermediate.
