教学目标:1.根据除法的意义,会用除法解决此类型的实际问题。2.继续经历解决问题的全过程,会从多余的信息中选取有效信息,积累解决问题的方法和经验,提高解决问题的能力。3.感受数学知识的内在联系,培养学生发现问题、提出问题的能力。教学重点:会选择有效信息,用除法解决实际问题。教学难点:建立用除法解决问题的模型,深化对除法意义的理解。.导学过程:
Teaching Objectives: 1. According to the meaning of division, will be used to solve this type of division of the actual problems. 2. Continue to experience the whole process of problem solving, select effective information from redundant information, accumulate methods and experiences in problem solving, and improve the ability to solve problems. 3. Feel the inner connection of mathematical knowledge, develop students to discover problems, ask questions. Teaching focus: will choose effective information, with division to solve practical problems. Difficulties in teaching: Establish a model to solve the problem with division, to deepen the understanding of the meaning of division. Guide process:
