教学目标:1.通过教学使学生能够掌握算24点的基本方法,在加、减、乘、除口算练习中,进一步提高口算能力。2.知道不同的牌可以算出24点,相同的牌有不同的算24点的方法,提高解决问题的策略和能力。3.增强学生学习数学的兴趣,进一步培养学生的创新意识和探索能力。教学过程:一、谈话导入,引入新课师:看!今天这节课老师给小朋友们带来了什么呀?对!是扑克牌。别小看这样的一副牌,它里面可藏着很多小
Teaching Objectives: 1. Through teaching so that students can grasp the basic method of computing 24 points, plus, minus, multiply, in addition to port arithmetic exercises to further improve the ability to speak. 2. Knowing that different cards can count 24 points, the same cards have different ways to count 24 points and improve strategies and abilities to solve problems. 3. To enhance students interest in learning mathematics to further develop students’ innovative awareness and exploration capabilities. Teaching process: First, the introduction of conversation, the introduction of a new class teacher: Look! Today, this class teacher to the children what is it? Do not underestimate such a card, which can be hidden inside a lot of small
