星期二,早自习加午自习,还有两节数学课,这是每一周里可以和孩子们一起尽情做数学的日子。一大早,看着孩子们陆陆续续到来,我给出一个任务:在白纸上尝试画一个平行四边形,并尝试把自己画的过程用文字表述出来,也可以借助图示来帮忙。四年级画平行四边形,虽然不是教材要求掌握的内容,但如果孩子们会画平行线,并且知道平行四边形对边相等等性质,那么他们一定能探索出方法。就当作是一次拓展训练吧。 There are two math classes on Tuesday and early morning study plus afternoon classes, a day where you can enjoy math with your children once a week. Early in the morning, looking at the kids coming one after another, I gave a task: try to draw a parallelogram on white paper and try to paint the process of painting their own words, you can also help with the icon. The fourth-grade parallelogram, although not a requirement of textbooks, will certainly find its way out if the children draw parallel lines and know that the parallelograms are equal on opposite sides. It is as an extension of training it.
