案例背景人教社义务教育课标实验教材以学生熟悉的、有趣的事情或故事创设情境,为学生提供了有利于观察、思考、猜想、动手操作的基本素材。面对全体学生,怎样深入挖掘、充分利用这些素材才能满足学生发展的需要呢?这是值得我们每位教师探索和深思的问题。在小学数学教材第二册第55页上,有一道关于买商品的开放题,笔者借此素材,结合生活实际,设计了《移民商店》这节课。这是一节练习课,也是一节活动课,主要是培养学生灵活运用数
Case Background Humanity education compulsory education curriculum standard experimental materials to students familiar with, interesting things or stories to create situations, provide students with the basic material conducive to observation, thinking, conjecture, hands-on operation. In the face of all the students, how to thoroughly tap and make full use of these materials to meet the needs of the students’ development? This is a question worth exploring and thinking deeply by each of our teachers. On page 55 of the second volume of primary school mathematics textbooks, there is an open question on the purchase of goods. Based on this material, the author designed the course “Immigrant Stores” based on the actual conditions of life. This is a practice class, is also an activity class, mainly to cultivate students to flexibly use the number
