Mô hình vật thật: thiết kế và sử dụng cho dạy học Toán

I would like to present our products to you. In fact, in the classroom, everyone will say that it is difficult and challenging. But what do teachers have to do to make students feel comfortable in the classroom by making practical models like this? So, these models I present here, all groups have clearly listed the uses as well as the groups have already done. However, I will say a little more. For example, when I give a picture like this and I ask the students to calculate the area around a figure like this. How do you calculate it? Obviously, in this picture, the students have not been able to learn and there is no method to do this. Of course, I will guide the students to learn one by one. The students will have to separate into two forms. One is the first form, which is a uniform triangle, and the other is a rectangle. The students will do and apply the method in the classroom. In this picture, as we can see, this is a rectangle. However, the special thing here is that we can change the position of the rectangle. We can remove it. And this model will be a model to represent an even triangle. And it will also help the students determine where the sides, the sides, the top and the surrounding points are. Of course, for this model, there are advantages and disadvantages in the process. I will highlight the difficulties here. The students need to be meticulous in creating the lines around so that when you draw the curve, it will not be broken on the paper. And how to combine colors to make it harmonious and accurate. And in the course, how to create the students' interest in the course will make the students feel more interested in the subject than the course. And this is the end of the class.
