From the beginning of the teaching design to the actual implementation of teaching students to explore as the main ideas, the development of mathematical thinking-oriented students, and achieved good teaching results.

In the thinking characteristics, mainly mechanical accumulation, problem solving is often imitation, lack of initiative
