The seventh unit of elementary mathematics The second unit of the fourth decimal Four multiplication of the second section, the textbook arranged 10 cases, the first six cases about the rules of decimal multiplication. Analysis and study of these examples should be carried out from the requirements of “double base”, the characteristics of each case, the arrangement level, the internal connection of each case and the prior and subsequent connection of knowledge, as well as the emphasis, difficulty and key of teaching materials.1. Requirements: According to the teaching requirements stipulated in the “Outline” and the contents of these examples, the “double basis” requirement for teaching this part of knowledge should be to enable students to understand and master the calculation rules of fractional multiplication and be proficient in the calculation of fractional multiplication. 2. The characteristics of each case and the level of arrangement: Analyze the solutions of each case in turn, recognize the emphasis, and understand the arrangement of the examples.
