首先,降低思考起点,推动无缝融合,让每个学生都充满自信。这一感悟来自《解决问题的策略——假设》的教学,来看我的两次设计。第一次:1.出示例题:全班42人去公园划船,一共租用了10只船。每只大船坐5人,每只小船坐3人。租用的大船和小船各有几只?学生读题,自我尝试解决。2.汇报交流解决问题的方法。3.总结学生解决思路的共同点:先假设再替换。4.试一试,尝试解决问题。 First, reduce the starting point for thinking and promote seamless integration so that every student is confident. This perception comes from the “problem-solving strategy - hypothesis” teaching, look at my two designs. First time: 1.Example example: The class 42 people go boating in the park, a total of 10 boats rented. 5 people sit on each big boat, 3 people sit on each boat. How many boats and boats are rented? Students read the questions themselves and try to solve them. 2. Report exchange to solve the problem. 3 summarize the common ground students to solve the idea: first assume replacement. Try it, try to solve the problem.
