本课时是在学生学习了因数、倍数的基础上,进一步来探索2、5的倍数的特征,并体会运用特征解题的优越性,明白优化知识的便捷性。一、联系生活,培养学生学习数学的兴趣在教学中,我拉近数学与生活的联系。首先利用“去电影院看电影这一教学资源,创设了问题情境,让学生利用手中的入场券分别从单号入口和双号入口进入电影院,从而观察双号的特点,由此
This lesson is based on the students to learn the factors, multiples of the basis to further explore the characteristics of multiples of 2,5, and understand the advantages of using the characteristics of problem-solving, to understand the convenience of optimizing knowledge. First, contact life, develop students interest in learning mathematics In teaching, I closer to the relationship between mathematics and life. First of all, using ”go to the cinema to see the movie as a teaching resource, we created a problem situation that allows students to enter the cinema from the single entrance and the double entrance respectively, so as to observe the characteristics of double numbers.
