第一步:导入新课,以“奇”引兴。开课前小学生注意力和兴奋点还留恋在课间的活动上,要使学生尽快收回注意力,教师开头语显得十分重要,在实践中我们采取了: 1.操作演示引新。讲解有关几何图形和推导计算公式,可以让学生亲自量一量、剪一剪、拼一拼、算一算,让小学生在玩中把知识学到手。 2.迁移引亲。讲解较复杂的应用题,先出现与新知识似同
The first step: to import a new class, with “odd” lead. Pre-course pupils attention and excitement also nostalgia in the activities of the class, in order to enable students to regain their attention as soon as possible, the teacher begins to say it is very important, in practice we have adopted: 1. The operation of a new lead.

Explain the more complex questions, first appeared with the same new knowledge
