3、趣味性和蕴含的问题性，同时让学生在活动中初步感受到球下落过程中不同的反弹结果。】小结：各种球从高处落下都会反弹，但是反弹的高度却不相同，这里有什么规律吗？下面我们就来探究这个问题。二、方案设计，探索新知。1、请大家先猜猜如果从同一高度落下，哪种球会反弹的高一些？（生自由发表自己的见解）2、提问：同学们的猜测是否正确，不同的球反弹的高度又分别是多少呢？想知道这些，我们需要怎么办？（引导学生认识到实验是检验真理的唯一标准，从而激发学生的实文档编码:CX3R5Q4S8B10 HI5S9C3R10P9 ZY7B1B2I3D3文档编码:CX3R5Q4S8B10 HI5S9C3R10P9 ZY7B1B2I

43、的反弹现象已经有了一定的实践经验，在此基础上，教材通过设计乒乓球、篮球落下时反弹的生活情境，让学生从中感知球从高处落地后都会反弹，并从这种自然现象中引发学生思考，探索一些实践问题：“球从同一高度落下，哪种球会反弹高一些？各自的反弹高度是多少？”引导学生通过实验进行科学探索，发现规律。学生通过参与这种实践性很强的活动，能有效积累和提升基本的观察、操作、体验、猜想探究、交流等数学活动经验，学会从不同角度分析问题、解决问题，拓展数学思维。2.学情分析（请按学生的实际情况进行补充）3.教学方法猜想验证法、小组合作法、多媒体辅助法。教学准备 教师：多媒体课件，充足气的气球、篮球、排球若干个，一个充气不足
