The purpose of the research was to recognize the reality of the application of the five mathematical operations recommended by the National Council of Teachers of Mathematics (NCTM) in Saudi kindergartens. It aimed at revealing the statistically significant differences for their application according to (geographical area/type of kindergarten/profession / academic qualification/years of experience), following the descriptive approach, as it was applied to a sample of (140) teachers (assistant -

... basic), supervisors, and principals, by constructing a questionnaire consisting of 13 phrases and suitable for the research subject. The research found that the percentage of approval by educational practitioners to apply these standards fell within a large limit, so the correlations came in the first place with a relative weight (96,3), followed by representation (74,3), then communication (62,3), and finally Problem solving (58,3), but the logical thinking criterion came within the average limit (3.11) and this ratio is considered insufficient as it is important for building mathematical concepts for the child. The research also revealed that there are no significant differences between the sample members about its application due to the research variables. The Research recommended reconsidering the mathematical curricula currently used in self-learning curricula according to Saudi and international development standards While preparing curricula.
