《全日制义务教育数学课程标准》指出:“学生的数学学习和活动应当是一个生动、主动和具有个性的过程。”下面,我就课堂中出现的两个片段发表自己的见解:一、一题多解,让数学贴近生活,走进生活教学完100以内的加减法后,我们遇到了这样一道很有争议的问题。题目是这样的:滑冰场原来有68人,有8人先走了,后来又有20人加入了,问现在滑冰场有多少人?孩子们都是这样列的算式:68-8+20(即先从总数里去掉走了的人,再加上后来又来的 The Full-Time Compulsory Education Mathematics Curriculum Standard states: “Students’ math learning and activities should be a vivid, proactive and individualized process.” Below, I make my own opinion about the two episodes that appear in the class: , A multi-solution, so that mathematics close to life, teaching life into teaching finished less than 100 addition and subtraction, we have encountered such a very controversial issue. The questions are as follows: There were 68 ice skating rinks, 8 of them were gone first and 20 of them were later joined. Ask how many people are there at the ice skating rink?
