Advantages:

1, review the clever design of the oral calculation link.

Oral arithmetic practice has become commonplace in mathematics practice. If students only answer orally, they won't be interested, but teacher Cong designed the form of "oral arithmetic king challenge". The teacher has 34 multiplication oral arithmetic problems in his hand, and the students answer, whoever answers more oral arithmetic problems correctly in one minute is the "king of oral arithmetic" today. Long-term training like this will cultivate students' ability to carefully examine questions and calculate quickly, so that multiplication formulas can be memorized and blurted out when they see questions.

2. Follow students' cognitive rules and arrange teaching steps reasonably.

Before learning the multiplication formula of 7, I had learned the multiplication formula of 2-6. The students all know the relationship between multiplication and addition and the origin of multiplication formula, so the teacher arranged the teaching steps of half-help and half-play in this class. When teachers and students sum up the formula of "372 1", the following formula requires students to write "How many are four sevens-how many are seven sevens?" The multiplication formula and formula are corrected by the whole class after the students finish writing. This arrangement of teaching steps not only cultivates the students' ability to explore new knowledge independently, but also optimizes the classroom time, so as to be targeted.

Disadvantages:

According to the teacher's teaching experience, it is found that students' listening habits and classroom routines are not good, which also requires teachers to make great efforts to cultivate students' learning habits in future study. No matter how good the class is, if the students don't listen, won't the teaching effect be greatly reduced?
