Mathematical situation is a bridge between real life and mathematics learning. Compulsory Education Mathematics Curriculum Standard (2011 Edition) emphasizes that mathematics teaching should be closely linked with the students ’actual life. Based on the students’ life experiences and existing knowledge, the creation of vivid Interesting situations. "Children in primary school are in the transition from concrete imagery to abstract logical thinking, and they prefer lively, interesting and intuitive things, while simple mathematical knowledge is abstract, boring, and an effective situation , Can make mathematics knowledge interesting, life taste, can fully stimulate student interest in learning, so that they gain understanding of mathematics
