两步计算应用题是简单应用题与三步(或多步)应用题联系的桥梁,是解答复合应用题关键性的一步。然后从简单应用题学习跨入两步计算应用题的学习,在小学生的思维活动中是一次飞跃。因为它不是两道简单应用题并列合并,而是二种数量关系的交叉组合。所以在教学垃程中,教师应该十分重视两步计算应用题的结构,应用题的数量关系,应用题的解题思路的训练。只有切实提高学生的解题能力,才能使学生对付今后学习中出现的种种困难,例如应用题中复杂的结构、
Two-step calculation of application questions is a bridge between simple application questions and three-step (or multi-step) application questions, which is a key step in solving complex application problems. Then from the simple application problem into the two-step calculation of the application of learning, in the thinking activities of primary school students is a leap forward. Because it is not a simple application of two parallel merger, but a cross between the two kinds of quantitative combinations. Therefore, in the teaching process, teachers should attach great importance to the two-step calculation of the structure of the application questions, the relationship between the number of questions, problem-solving train of thought questions. Only by effectively improving students' ability to solve problems can students be able to deal with the difficulties that arise in their future study, such as the complicated structure of application questions,
