导入新课是小学数学教学过程中必不可少的重要环节。“善始者事半成”,要在短暂的二至三分钟内做到习旧引新,使学生迅速进入最佳的学习状态,需要采取一定的方式来实施。根据数学学科的特点和儿童认识事物的规律,笔者就导入新课的三种方式及设计,谈一点个人的做法,供老师们教学时参考。一、组合式的导入要注意“巧”
Importing a new lesson is an essential part of primary school mathematics teaching. “Good things happen half-done”, in a brief two to three minutes to do the old habits, so that students quickly into the best learning state, need to take some measures to implement. According to the characteristics of mathematics and the law of children's understanding of things, the author will introduce three new courses and design, a little personal approach for teachers to teach reference. First, the combined import to pay attention to “clever”
