一、创设情境,提出问题师:星期天,聪聪和爸爸乘车到超市购物,(课件呈现场景)聪聪看着平行四边形的停车位,小脑筋就转了起来,你知道他在想什么吗?师:你会计算这个平行四边形停车位的周长吗?怎样计算(?给出图形数据,学生计算)师:周长会计算了,那它的面积该怎样计算?今天,我们就一起来探究平行四边形面积的计算方法。(揭示课题)[设计意图]创设现实的、生动的生活情境,加强了数学与生活的联系,让学生感受到数学就在身边, First, the creation of the situation, ask the question division: Cong, Cong and dad ride to the supermarket shopping, (courseware presents the scene) Cong Cong looked at the parallelogram parking spaces, the brain began to spin up, you know what he was thinking Teacher: Will you calculate the perimeter of this parallelogram parking space? How to calculate (? Given graphic data, student calculation) Teacher: Perimeter will calculate, then how to calculate its area? Today, we will explore the parallel Quadrilateral area calculation method. (Reveal the subject) [design intent] to create a realistic and vivid life situation, strengthen the connection between mathematics and life, so that students feel that mathematics is around,
