教学重点难点是学生在课堂上认知的焦点,因而解决重点,化解难点是教学成败的关键。1.联系生活,变陌生为熟悉。在我们的生活中,数学无处不在。因此,在数学教学中,教师尽量创设情境让学生走进实际,走进生活,时刻将数学与生活紧密结合起来,让数学在学生的眼里变成看得到、摸得着、用得上的学科,从而使学生从枯燥的公式中、从抽象的符号中解脱出来,在让学生从自己的身边找出直观、熟悉的答案。如在学习“厘米和米的认识”时,让学生建立1厘米和1米的表象过程中,教师先让学生动手量量生活中1厘米和1米的物体,再让学生说一说生活中与
The key point of teaching is the focus of students’ cognition in the classroom. Therefore, solving the key points and solving the difficult points are the key to the success or failure of teaching. 1. Contact life, become unfamiliar to become familiar. Mathematics is everywhere in our lives. Therefore, in mathematics teaching, teachers try their best to create situations for students to walk into the real life and combine mathematics with life closely so that mathematics can be seen, touched and used in the eyes of students Subjects, so that students from the boring formula, from the abstract symbol of freedom, allowing students to find out from their own intuitive, familiar answer. For example, when learning about the concepts of centimeter and meter, letting students create appearances of 1 centimeter and 1 meter, the teacher first lets the students measure the objects of 1 centimeter and 1 meter in their daily life, let the students talk about it In life
