【Abstract】Primary school mathematics,as a key subject for the development of students' intelligence,cultivating students' mathematical thinking and logical thinking,etc.,plays a vital role in learning at the elementary level. The setting of application questions is the best presentation of elementary school mathematics in developing students' intelligence,cultivating mathematical thinking and logical thinking. However,in practical applications,students have a variety of answering questions in the answers to application problems. Based on the design intent of application problems,this article analyzes the common problems of primary school mathematics application problems,and explores the effective strategies of primary school mathematics application problems in the actual answering and teaching process.

小學数学试卷是由填空、判断、选择题、计算题和应用题五大板块构成的,其也是有简到难的设计方式。数学应用题作为压轴出场,其难度主要在于需要学生运用严谨的阅读思考对题目做出正确判断,这是破解应用题的关键。数学应用题的设计大多贴合日常生活实际,数学问题也涉及常见生活问题的思考。伴着数学应用题的常规出现,学生对于数学应用题的解题和利用所解答的应用题去解决日常生活中的实际问题则是关键。为了更好地帮助学生运用所学的数学应用去解决生活问题,有效的数学应用教学方式则成为教师教学不断革新、不断求取新的方法,也为进一步增加学生对于数学应用的兴趣做了铺垫。1.数学应用题设计存在的积极意义
(1)注重学生的思辨性。数学应用题设计存在的意义之一就是注重学生的思辨性。……
