For example, the student explained the shortening: âWe divide the top and the bottom by the same number. "The teacher immediately pointed out that he had to express himself correctly. He asked the rest of the class what we call the "top" and "bottom" of the fraction. Here I realized that it is important for students to explain and express mathematics in class. Throughout the repetition, the teacher made sure that the missing students understood the subject matter. The whole activity lasted less than 15 minutes and I think it served its purpose well.
