新理念告诉我们,要让学生“做”数学,“用”数学,让学生通过自己仔细地观察实验,收集事实证据,提出和求证的假说,在亲自动手操作、触摸感知实物材料的过程中,体验知识创造的乐趣。这个过程,也是个体充分发挥自己的想像与创作的过程。动手“做”数学,平面图形、立体图形的推导可动手做,如平行四边形、三角形、梯形、圆面积公式的推导,长方体、圆柱体、圆锥体体积的推导,都可以让学生亲自体验问题的发生、形成、发展过程。除此之外,有些概念、应用题的理解,也可以让学生动手操作。例如:“平均数概念”的教
The new concept tells us that let students “do” mathematics, “use” mathematics, let students observe the experiment by themselves carefully, collect the factual evidence, put forward and verify the hypothesis, in hands-on operation, touch the perception of physical materials, Experience the fun of creating knowledge. This process is also an individual’s process of giving full scope to his own imagination and creation. Doing “doing” math, plane graphics, the deduction of three-dimensional graphics can do hands-on, such as the parallelogram, triangle, trapezoid, the formula of the circle area deduction, cuboid, cylinder, cone volume deduction, can let students experience the problem Occurrence, formation and development process. In addition, some concepts, application of understanding, but also allows students to operate. For example: “Mean concept” teaching
