《小学数学新课程标准》中指出,数学教学活动必须激发学生兴趣,调动学生积极性,引发学生思考,要注重培养学生良好的学习习惯,掌握有效的学习方法。作为教师,要想在达到标准的情况下进行教学,让学生学到更多的知识,就要丰富课堂内容,让教学变得更加有趣,从而使学生更加积极地进行学习和知识的吸收及转化。那么,使课堂变得生动有趣就成了教师首要的任务。 The “New Curriculum Standards for Primary Mathematics” states that mathematics teaching activities must stimulate students ’interest, arouse students’ enthusiasm, trigger students ’thinking, pay attention to cultivating students’ good study habits and master effective learning methods. As a teacher, if you want to teach under the standard and let the students learn more, enrich the contents of the class to make the teaching more interesting so as to make the students more active in learning and knowledge absorption and transformation . Then, making the classroom lively and interesting has become the primary task for teachers.
