几何初步知识教学有利于培养小学生的空间观念,提高学生用数学知识解决问题的能力,培养学生初步的逻辑思维能力。而几何求积是几何初步知识教学的重要内容。因此,指导学生进行几何求积时,应使用适当的教学策略。一、建立对周长、面积和体积的初步认识在学生初步认识长方形的周长时,教师可让学生准备好细铁丝或小棒等,通过绕一绕、搭一搭,完成一个基本的长方形;再进一步让学生观察教具——长方形框架,让学生用手绕
The teaching of elementary knowledge of geometry is conducive to cultivating the concept of space for pupils, improving students’ abilities to solve problems with mathematical knowledge and cultivating their initial logical thinking ability. The geometry of product geometry is an important part of the initial knowledge of teaching. Therefore, to guide students in the geometric quadrature, you should use the appropriate teaching strategies. First, the establishment of the perimeter, area and volume of the initial understanding of the students initial understanding of the perimeter of the rectangle, the teacher can allow students to prepare fine wire or small stick, etc., by winding around, take a ride to complete a basic rectangle; To further allow students to observe the teaching aids - rectangular frame, so that students around with hands
