数学教学是培养学生思维能力的主要平台,而数学课堂练习又是数学课堂教学中的主要组成部分,它也是培养学生思维能力、提升学生数学技能的重要抓手,学生可以在数学课堂上通过不同的练习,来训练思维。但是在平时的数学练习教学中,我们教师过多追求的是标准答案,练习题的设计过于单一、呆板,学生在这样的数学练习中思维往往受到条件或问题的限制而得不到有效发展,而开放数学练习就可以更好地提升学生的思维能力,所以,我们要开放数学练习,让教材中的知识点与我们的开放性练习结合起来,优化学生的认知结构,给予学生一定的时间与空间来动手、 Mathematics teaching is the main platform for cultivating students’ thinking ability, and mathematics classroom practice is the main part of mathematics classroom teaching. It is also an important starting point for cultivating students’ thinking ability and improving students’ math skills. Students can use different mathematics classes Practice, to train thinking. However, in normal practice of mathematics practice, we teachers seek too much standard answer, the design of exercises is too simple and inflexible, students in such mathematical exercises are often limited by the conditions or problems and can not be effectively developed, Open math exercises can better enhance students ’thinking ability. Therefore, we should open math exercises, combine knowledge points in teaching materials with our open practice, optimize students’ cognitive structure and give students a certain amount of time Hands-on with space,
