The study aims to identify the effectiveness of Reciprocal Teaching Strategy on mathematical communication skills development of first grade intermediate students. The researcher has adopted the quasi-experimental approach by forming two groups (experimental group and control group) study sample has been selected by Purposive method where study sample consisted of (49) students, divided into two groups, the experimental group (25 students) and the control group (24 students). Researcher has gathered the research material and tools consisted of teacher guide, student activity book and mathematical communication skills test. The results has shown statically significant difference at significant level (0.05) between the intermediate marks of the two group (the experimental group and control group) in the after mathematical communication test at skills: mathematical thinking organizing, representing the mathematical relationships and actions in different manners, passing the mathematical phrases in coherent manner to others, analyzing and correcting mathematical solutions and discussions offered by others, using the mathematical language for describing and expressing the mathematical thoughts in a clear manner, and the total exam marks were for the experimental group with high effect size where Eta Squared were (0.32, 0.20, 0.18 , 0.32, 0.34) respectively.
