The introduction of classroom design, it is necessary to consider the specific content of teaching, but also pay attention to the form and method, which is to improve classroom teaching efficiency, optimizing classroom teaching one of the important steps. First, the old introduction of new, surprisingly surprising In primary school mathematics teaching, the teaching of new teaching generally should be based on old knowledge, especially in the same section with a few sections of the class is more closely linked. Encounter such a lesson, we should find the connection point of old and new knowledge, plain
