[Design concept] mathematician Hua Logeng said: “This is the universe, the micro-particles, the rocket speed, the cleverness of the earth, change of the earth, the complex of daily use, everywhere mathematical.” This is a mathematical and life Wonderful description. Mathematics teaching and social life interdependence, mutual integration. Therefore, learning mathematics, can not just stay in the knowledge of learning, but must learn to apply. Emphasis on application, in order to make mathematics learning full of vitality. Supiao version of the six “discount problem” a lesson, based on life, based on the students’ existing knowledge level, so that students understand the extensive use of mathematics in life. First, with the characteristics of teaching materials to show the charm of mathematics
