Through measurement lessons, Dafa showed good progress in understanding the concept of angles. He can now read the angles formed by clock hands accurately through practice using an angle clock learning tool. With the help of this teaching aid, Dafa can visually and independently recognize and determine the size of the angles formed by the movement of the clock hands. During the activity, he looked more confident and enthusiastic in joining the classroom lesson. This progress shows that Dafa’s understanding of measurement concepts is developing well.
