在小学数学教学中,教师要做的不是教给学生题目的答案,而是解题思路和数学思想。小学正是帮助学生打好数学基础的关键时期,因此,教师要逐步将数学思想渗透到教学中去,让学生真正理解和掌握一些数学思想,促进学生的发展。化归思想是数学思想中一种重要的解题思想,它是指将一个问题由难化易、由复杂化为简单的过程,从而帮助解决问题。那么,如何在小学数学教学中巧妙地运用化归思想呢?一、化曲为直,突破空间障碍
In primary mathematics teaching, teachers do not teach students the answer to the subject, but the problem-solving ideas and mathematical thinking. Primary schools are just a crucial period to help students lay a good foundation for mathematics. Therefore, teachers should gradually penetrate mathematical ideas into teaching so that students can truly understand and master some mathematical ideas and promote their development. The idea of returning to normalization is an important problem-solving thought in mathematical thought. It refers to helping to solve a problem by changing one problem from difficulty to easiness to complexity into a simple one. So, how to skillfully use the idea of returning to normalization in primary mathematics teaching? First, the song is straight, breaking the space barrier
