我教小数乘以整数(五年制课本第七册)这个内容时,有意识地对学生加强推理能力的训练,现在谈谈我的做法: 一、引导学生归纳出计算法则。教材对小数乘以整数计算法则的揭示,主要是运用因数和积的变化规律说明算理的,我在教学时,增加了训练学生归纳推理的内容。我考虑到仅从一两道题的计算,是难以归纳出结论的,所以在原来例题的基础上编了如下题目给学生思考: 1.养猪专业组的猪,
When I teach fractional numbers multiplied by integers (the fifth volume of the textbook, Volume 7), I consciously train my students to improve their reasoning ability. Now let me talk about my approach: First, guide students to generalize the law of calculation. Teaching materials on the decimal multiplied by the integer law of the revelation, the main factor is the use of the law of change and product description, I teach teaching, increased training inductive reasoning content. I consider that only from a calculation of one or two questions, it is difficult to conclude, so in the original example based on the following topics for students to think: 1.
