“数学活动”是全日制义务教育数学《标准》新开设的模块,作为一线的数学教师应该积极投入“数学活动”的研究之中,使“数学活动”真正成为数学教学的一个组成部分,成为一种有效的教学形式。笔者就“全等三角形”的数学活动课做了一些尝试,现做如下例析。【活动过程】在前面全等三角形的学习中,我们知道全等三角形就在我们的身边,数学无处不在。而我们学习数学的目的,也正是为了解决生活中的实际问题。现在就有这样一个问题需要大家来解决,我们一起来看
Mathematic Activity is a newly established module of full-time compulsory education mathematics standard. As a first-line mathematics teacher, it should be actively involved in the study of mathematics activity so that mathematics activity can become a truly mathematical teaching As an integral part of an effective teaching form. The author made some attempts on the “congruent triangle” mathematics activity class. 【Activity process】 In front of the congruent triangle learning, we know that congruent triangles are on our side, mathematics is everywhere. The purpose of our study of mathematics, it is also to solve the practical problems in life. Now there is such a problem we need to solve, we look together
