Content compulsory education curriculum standard experimental textbook mathematics grade three P42 cases 1. Textbook from the real life, select the students around the case, the life of material throughout the entire teaching activities from beginning to end, follow the mathematical origin, life, for life concept. Let students learn to use the average in practical hands to compare the overall situation of two groups, to understand the relationship between mathematics and life. Academic analysis At this time, although the students have preliminary information analysis, processing, and ability to solve. However, their thinking is still in the transitional period from concrete image to abstract logical thinking.
