引论:小学数学教学应结合小学生的认知发展水平和已有的知识经验展开,为学生提供充分从事数学活动的机会,帮助他们在自主探索和合作交流的过程中真正理解和掌握基本的数学知识与技能、数学思想和方法,获得广泛的数学活动经验,真正让课堂数学“活”起来。案例1:《除法的初步认识》教学片段学生被分为6人一小组,每人手上有6根小棒。A教学:师:大家手上都有6根小棒。平均分成三份,每份是多少呢? Introduction: Mathematics teaching in primary schools should be based on the level of cognitive development and existing knowledge of primary school students to provide students with the opportunity to fully engage in mathematical activities to help them understand and master basic mathematics in their own exploration and cooperation and exchange. Knowledge and skills, mathematical ideas and methods, access to a wide range of mathematical activities experience, the real classroom mathematics “living ” up. Case 1: “A Preliminary Understanding of Division” Teaching Fragments Students are divided into 6 small groups, each with 6 small sticks. A Teaching: Teacher: Everyone has 6 small sticks on hand. The average is divided into three, how much is each?
