A successful math class is like playing an entertaining and dripping piece of music, and the listener is mesmerized. The beginning of a class is just like the beginning of a piece of music, and the authoritative violin playing “Butterfly Lovers” in our country Yu Lina paid special attention to the accuracy of the first note of the tune, so that her performance has been difficult to surpass others so far.And to the introduction of math class in high school, our front-line teachers should not only pay attention to the study and update of the classroom introduction method, but also Should be combined with the actual teaching, continuous reflection, improve the skills of the introduction of the classroom, with students to play a successful musical movement.The following teaching reflection is that when I participated in the 2011 Shandong Province High School teaching contest, the “zero” "A section of the new course into the process of revision
