《数学课程标准》指出:“义务教育阶段应突出体现数学的基础性和发展性。”“应重视口算,加强估算,鼓励算法多样化。”在小学阶段,学生计算速度的快慢和正确率将直接关系到成绩的好坏。要想提高学生的数学成绩,就得从学生的计算抓起。一、坚持课前3-5分钟练习教师不论是上什么样的教学内容,在备课的环节中都要设计上口算练习这一环节。授新课前,可坚持用3-5分钟时间搞口算基本训练。这种课堂口算训练形式,要求学生合
The Standard of Mathematics Curriculum states: “The compulsory education phase should highlight the foundation and development of mathematics. ” “We should attach importance to port count, strengthen estimation and encourage algorithm diversification.” In the elementary school stage, students calculate the speed of the speed And the correct rate will be directly related to the performance of good or bad. If you want to improve students’ math performance, you have to start from the student’s calculation. First, insist on 3-5 minutes before class practice teacher no matter what kind of teaching content, in the preparation of the link must be designed to catch the word practice this link. Teach a new class, you can insist on 3-5 minutes with basic training. This type of oral training in the classroom, requiring students together
