教学目标：1、知识与技能目标：通过学生探索两位数乘两位数（不进位）估算、口算和笔算方法的活动，使学生经历理解算理的过程，以逐步掌握算法、形成技能。
2、过程与方法目标：学生通过自主探索、合作交流，进一步理解算理，体验算法。
3、情感态度与价值观目标：在探索算法与解决问题过程中，增强合作交流的意识，体验成功的喜悦。
教学重点：在理解算理基础上掌握两位数乘两位数（不进位）的笔算方法。
教学难点：理解笔算乘法的顺序与第二部分积的书写方法。
教学准备：多媒体、答题纸教学过程：一、创设情境，生成问题。
小红和大家一样，也是一个非常爱读书的孩子，星期天她和妈妈一起来到书店买书，从图中你知道了哪些数学信息？（一套书12本，每本24元。
）师：根据这些信息，你想提出一个什么问题？【设计意图：从学生的想法出发，让他们发现问题，提出问题，体现学生的自主性。
】预设生：一共花多少元？师：这也是小红正在思考的问题。
（出示）你们能解决吗？怎样列算式？学生列算式，师板书24×12师：这是一道几位数乘几位数的算式？师：前面我们已经学习了两位数乘一位数和两位数乘整十数，那像24×12这样的两位数乘两位数的算式又该怎样计算呢？今天这节课我们继续来研究两位数乘两位数。
（揭示课题：两位数乘两位数）【设计意图：引起学生的认知冲突，激发起学生学习的兴趣。
】二、理解算理，探究算法。
1、在估算的基础上口算出实际得数。
师：大约一共花了多少钱呢？你能估算一下吗？（1）预设3种估算方法，口算出得数生1：把12估成10,24×10=。
请学生思考，这个是估大了还是小了？（小了）为什么？引导学生理解：把12估成了10，实际上算的是几本书的价格？（10本）那要计算一共花多少钱，还要怎么做呢？学生说想法，演示帮助理解。
