Abstract. This study used a model of Concurrent Embedded with the aim of: The aim of this study was to know mathematical conection on linier equation of one variable with contextual learning, then observed that mathematical connection. This study used mixed method research. Instrument that used in this study were observation, interviews, and test. Subject of this study was students at SMPN 6 Jepara with VII E as experiment class and VII D as control class. The results showed mathematical connection at experiment class with mathematical connection between concepts in material indicator was 92.6%, the ability of the connections between topics indicator was 80.1%, the ability to connect with other subject indicator was 63.2%, and the ability to connect with their daily lives indicator was 82.9%. Whereas, mathematical connection at control class with mathematical connection between concepts in material indicator was 82.7%; the ability of the connections between topics indicator was 60.1%; the ability to connect with other subject indicator was 58.1%; and the ability to connect with their daily lives indicator was 28.1%. Based on that results the ability of mathematical connection to connect with the daily life because of contextual learning. Keywords: mathematical connection, contextual learning
