Specifically, in this activity, the junior grade group carried out the 'rapid calculation competition' while the middle and senior grade groups conducted the 'mathematical thinking competition'. In the examination room, the students meticulously examined the questions and focused on answering the questions. For instance, some students lowered their heads and thought carefully; Some were full of confidence and worked hard and some students frowned, thinking hard. Evidently, everyone was doing their best to showcase their levels.

To put it in a nutshell, this activity has created a good learning atmosphere, tapped the potential of students, and enhanced their interest in learning and using mathematics. Meanwhile, this activity promoted the development of students' thinking ability, so that they were willing to explore, innovate and think deeply.
