在新课程改革的实施过程中,许多学校和教师在小学数学教学中仅关注课堂教学方式手段的创新和教材教学内容的改革。为了提高小学生的数学素养,教师应把数学教学向书本外、向课堂外拓展。对运用主题拓展方式来丰富小学数学课程教学样式进行了实践探索,希望对提高学生数学素养能起到有益的帮助。 In the process of implementing the new curriculum reform, many schools and teachers pay attention to the innovation of the means of classroom teaching and the reform of the contents of teaching materials in elementary mathematics teaching. In order to improve pupils’ math literacy, teachers should extend mathematics teaching outside of the book to books. This paper makes a practical exploration on enriching the teaching style of mathematics curriculum in elementary schools by using the method of theme expansion, hoping to help students improve their mathematical literacy.
