Data were analyzed using Mann-Whitney Test, Wilcoxon Signed Ranks Test, and Cohen's d. The findings are: There were no differences between the mean scores of the children of the control group in the pre- and post-test. There were differences between the mean scores of children in the experimental group in the pre- and post-test in favor of the post-test, and between the mean scores of children in the control and experimental group in the post test in favor of the experimental group. Great effectiveness of the mathematics center was shown. The researcher recommends motivating teachers to establish math centers in classes for their effective impact on learning. It is essential that teachers make use of the standards’ document in all its levels with more concern about cognitive fields, to be presented through developmentally appropriate practices in the daily program and especially during centers’ time.
