一、资源1.数学课堂当学生学过新知识后,可以通过写数学日记,加强对知识的巩固和深化,促进学生的发展。如学完“认识三角形”后,学生写了这样两则数学日记:(1)我觉得“三角形的稳定性”在生活中常常要用到,比如高空搭建建筑模板,还有衣架等一些生活用品的设计。(2)知道三角形的内角和,我们可以求其他多边形的内角和,是不是所有多边形都可以分解成三角形呢?多边形越来越接近圆,那为什么反而圆的度数比较小呢?通过数学日记的方式,可以使学生
I. Resources 1. Mathematics Class After the students learn new knowledge, they can strengthen the knowledge consolidation and deepening through the writing of diary of mathematics to promote the development of students. After finishing “Understanding the Triangle”, the student wrote two mathematical diaries like this: (1) I think “stability of the triangle ” is often used in life, such as the construction of high-altitude building templates, as well as hangers And so on the design of daily necessities. (2) Knowing the interior angles of triangles, we can find the interior angles of other polygons. Can not all polygons be broken into triangles? Polygons are getting closer and closer to the circle, so why is the circle smaller? Way that can make students
