The use of rulers by students plays an important role in their learning process. By understanding different types and functions of rulers, as well as correct usage methods and selection skills, students can better use rulers to complete various learning tasks, improve learning efficiency and quality. Therefore, it is recommended that students choose a suitable student ruler according to their own needs, making it a good partner in their learning and life.

The teaching scale set also has ease of use and flexibility. Teachers can choose or design a teaching scale set that suits their actual needs. In the evaluation process, teachers only need to score or rate students' performance based on the indicators and scales on the scale, which is simple and convenient to operate. At the same time, the teaching scale set can also be adjusted and modified as needed to meet the teaching needs of different subjects and grades.
