小学数学是小学课程中的重点内容,同时也是难点内容。由于数学具有抽象性和严谨性的特点,学生在数学学习上难免会存在一些不理解的问题。所以,教师在教学中应该加强对学生的引导,帮助学生进行数学学习和提高。以解决学生在数学学习中面临的问题,提高学生数学能力为中心,探讨发挥数学教学“有效性”的途径十分重要。 Primary school mathematics is the focus of primary school curriculum, but also difficult content. Due to the abstraction and rigor of mathematics, students will inevitably have some problems in mathematics learning that they do not understand. Therefore, teachers in teaching should strengthen the guidance of students to help students learn mathematics and improve. In order to solve the problems that students face in math study and to improve students’ math ability, it is very important to explore the ways of teaching math teaching “validity”.
