师：同学们好，今天我们上课的内容是三年级发展速度、力量素质练习。本节课的学习目标是掌握发展速度与力量数值的练习方法，通过游戏练习提高快速移动和下肢力量数值，养成自觉锻炼、主动探索的习惯，提高自信心和创造力。上课前，请同学们穿好运动服和运动鞋，收拾出一块安全的活动场地，准备好10张小卡片或者扑克牌。如果家里面有小纸巾包、一些立式封还有小纸卡都可以用上，写上1 - 10的数字就行。还没准备好的同学，赶快准备，老师相信你们很快就能准备好，加油。接下来，我们一起进行这节课的热身活动。如果同学们已经准备好，请跟老师一起做准备活动，老师做的是镜面试范，请跟老师同一方向，跟好节奏。

师：大步。调整呼吸，再来一次。好，完成热身活动后，请同学们把刚才准备的扑克牌、小纸卡这些器材拿出来。老师已经准备好了，你们呢？如果准备好了，我们就进入第一部分快速移动的学习。在日常生活中，我们会遇到一些突发情况，需要快速移动、紧急避险。大家看，这节课的小助手螃蟹先生已经迫不及待跟我们打招呼了，我们也跟它打个招呼吧。
师：好，螃蟹先生说我们这节课要进行螃蟹走的练习，大家要模仿螃蟹先生进行螃蟹走。先把扑克牌放在活动中心点位置的前面，然后把自己想象成一只大螃蟹。螃蟹走的时候，双脚左右打开，微微弯曲膝盖，双手在体侧自然伸展开，左右移动的时候重心也要跟着移动。好，加快速度，向左向右、向左向右，向左向右。同学们，我们一起跟着螃蟹先生再练习一遍，好吗？准备开始，左右，重心跟着移动起来。左右，同学们，你们真棒，相信你们一定学会了。
