In fact, as early as the first year of understanding the number of less than 10, the students have unconsciously applied the enumerated strategy to discuss a certain number of a total number of different decomposition method; in the “graphics and geometry” , “Statistics and probability” content of the learning process, but also many times unconsciously applied enumerated strategy
