在教学人教版实验教材的“两位数加两位数”时,我们做了如下处理:为了解决课本上没有处理为什么从个位加起的问题。我们把三个例题压缩成两个例题,以便给学生留出更多的讨论、交流的空间和时间。教学过程大致是这样的:引出35+3436+35两个算式后:师:咱们研究35+34=?能不能用摆小
In the teaching of PEP teaching materials “double-digit plus two-digit”, we did the following: In order to solve the textbook did not deal with why the problem from the first place. We have compressed the three examples into two examples to give students more room for discussion, exchange and time. The teaching process is roughly like this: leads to 35 + 3436 + 35 two formulas: division: let's study 35 + 34 =?
