如何才能让数学思考在计算教学中流淌呢?现以“用2~6的乘法口诀求商”教学为例,谈点管见。一、问题呈现:直白式问题作留白式处理,唤醒学生数学思考的诉求新课程背景下计算教学的编排虽然寓于问题解决之中,但最终是为促进学生的数学思考服务的。本课教材提供的例题条件充分、问题直白,学生只要根据题意就能列出算
How to let mathematical thinking flow in the calculation of teaching it? Now to “use 2 to 6 multiplication formula to find business” teaching as an example, talk about the tube see. First, the problem is presented: Straightforward question to be treated as a whistle-blow to arouse the students 'demands for mathematical thinking Under the background of the new curriculum, computational teaching is arranged to solve the problem, but in the end to promote students' mathematical thinking services. The teaching materials provided by the examples of the conditions are sufficient, the problem straightforward, as long as the students according to the title can be listed
