Abstract

: The current research aims to prepare a performance scale to measure the geometric thinking of kindergarten children. The scale consists of 20 phrases that measure the first three levels of geometric thinking; They are (the level of visual recognition analysis, and non-formal inference), and the descriptive approach and the statistical approach were used to verify the extent to which the geometrical thinking scale has psychometric properties (reliability and validity). The internal homogeneity of the scale, to check the validity of the scale, Cronbach's alpha stability coefficient was used, the split-half method, and the research sample was selected from kindergarten children -the second level -, and their number reached 150 boys and girls between the ages of (6 - 7) years . The results of the research revealed that the performance engineering thinking scale for kindergarten children enjoyed a high level of reliability and validity .
