The research aims to develop some mathematical concepts in kindergarten children through the use of the Reggio Emilia curriculum based on life situations. The research sample consisted of (60) male and female children from the second level of kindergarten, whose ages ranged from (5-6) years. They were divided as follows: The experimental group consisted of (30) male and female children, and the control group consisted of (30) male and female children. The experimental method was used, and the research tools were determined in the illustrated mathematical concepts scale for kindergarten children (prepared by the researcher), a program based on the activities of the Reggio Emilia curriculum based on life situations for kindergarten children (prepared by the researcher). The results showed that the use of the Reggio Emilia curriculum based on life situations in developing mathematical concepts in kindergarten children
