【Abstract】Intuitive geometry teaching can not only make boring mathematics learning easier and more enjoyable, but also enable students to improve their mathematics literacy in such a learning process. As a primary school mathematics teacher, students should be given the opportunity to learn independently and practice on their own initiative, so that every student can improve their mathematics literacy in the intuitive teaching of geometry. In the specific course teaching, teachers can carry out teaching activities from the combination of number and shape, physical display and practical activities to improve the effectiveness of classroom teaching.

數学学习内容比较枯燥,如果在几何教学中也采取枯燥的讲解策略,那么,学生接受知识就会被动,毫无情感的学习是没有良好的效果的。《义务教育数学课程标准(2011年版)》明确将直观几何纳入了重点概念之一。新课程改革实施以来,学生的主体学习地位备受关注,而教师应引导学生学会利用直观几何的概念处理各种数学问题,化繁为简,使学生的空间思维能力、数形结合能力与数学分析能力之间建立起必然的联系,使学生能够在直观的学习中感受到数学的形象性。针对小学数学教学现状,教师应该充分运用直观教学形式,将较难理解的几何知识直观化,帮助学生更好地学习和理解几何知识,具体可以从数形结合、实物展示以及实践活动等方面开展教学活动,让每个学生都可以积极参与数学课堂学习活动中,收获学习的快乐和自信。文章基于小学几何直观教学经验,将从以下几点进行有效探讨。……
