要进行创造性活动必须具备逻辑思维能力。在数学教学中,要尽量让学生动手、动脑、动口,给学生提供必要的感性材料,为学生的创造性思维寻求源泉。在教学“长方体的表面积”时,让学生把准备好的长方体纸盒沿着棱剪成六块,分别有三个二块相等。教师的任务是引导,帮助学生再创造。学生发现:只要求出不同的三块长方形的面积,就能求出长方体的表面积,
To carry out creative activities must have logical thinking ability. In mathematics teaching, we should try our best to let the students start their own activities, move their brains and move their mouths to provide the students with the necessary sensuous materials and seek the students’ creative thinking. When teaching “the surface area of the cuboid”, let the students cut the prepared rectangular parallelepiped paper box into six pieces along the edges, with three pieces of two equal pieces respectively. The teacher’s task is to guide and help students to recreate. Students found that as long as the area of the three different rectangles is determined, the surface area of the cuboid can be calculated,
