较复杂的分数应用题,题型广博,变化多端。在教学中,我们应适当地教给学生一些解题方法,以拓宽思路,提高解题能力。一、从确定对应入手找出解题方法分数应用题中有一个“量率对应”的明显特点,对一个单位“1”来说,每个分率都对应着一个具体的数量,而每一个具体的数量,也同样对应着一个分率,因此,正确地确定“量率对应”是解题的关键。我们要引导学生学会和掌握“明确对应,找准对应分率”的解题方法。例:小冬看一本故事书,第一 More complicated questions, wide range of questions, varied. In teaching, we should properly teach students some problem solving methods to broaden their thinking and improve their ability to solve problems. First, determine the corresponding response to find a solution to the problem There is a “application rate-response” in the application of the question, for a unit “1 ”, each rate corresponds to a specific number , And each specific number, also corresponds to a fraction, therefore, to correctly determine the “volume rate corresponding” is the key to solving the problem. We should guide students to learn and master “clear correspondence, identify the corresponding score ” problem-solving method. Example: Xiaodong read a story book, first
