From the characteristics of mathematics, students learn mathematics knowledge is the result of previous thinking. Learning this knowledge is not a simple absorption, but must be through their own thinking, the thinking of the previous person into the results of their thinking. Teachers’ task is to guide and help students to recreate rather than instill ready-made conclusions to students. Allow students to explore the unknown areas in the process, to pay the previous discovery of these knowledge have been paid by the same intellectual costs, so as to effectively realize the value of knowledge training intelligence.
