【教学内容】北师大版一年级下册第七单元《套圈游戏》【教材分析】本节课是在学生已经学习100以内加减法运算基础上进行教学的。教材通过学生喜闻乐见的套圈游戏情境,来引入100以内数的连加学习,以此激发学生学习数学的兴趣,进一步体验数学中的算法多样化,并渗透估算意识的培养。同时为进一步学习100以内连减、加减混合运算打下基础。
【Content】 Beijing Normal University version of the first grade Volume VII seventh unit “Rings game” 【Textbook Analysis】 This lesson is in the students have been learning to add or subtract less than 100 operations based on teaching. Teaching materials through the love of students loved by the context of the loop game to introduce the number of even less than 100 plus learning, in order to stimulate students interest in learning mathematics to further experience the diversity of algorithms in mathematics, and penetration of training in the development of estimation. At the same time to further study less than 100 with the addition and subtraction hybrid computing laid the foundation.
