In this week's teaching and research activities, our sixth grade math group prepares lessons for the third unit of the first volume of the sixth grade, Division of Fractions. First of all, Liu Fang, the leader of the teaching and research group, talks about the teaching and research process. Then, Mr. Ge analyzed this unit from three aspects: teaching materials, objectives and teaching. Next, we discussed and exchanged this unit with our own teaching practice. Teachers spoke actively and put forward their own golden ideas. Finally, our director Liu made a comment, which not only affirmed that the activity was very effective, but also put forward pertinent suggestions. We should study the curriculum standards in depth and learn the teaching materials from the curriculum standards.

Through this collective lesson preparation seminar, it provides good teaching ideas and strategies for the teaching of this unit. Collective lesson preparation can lead to the collision of participants' wisdom, learn from each other's strong points and supplement the lack of professional knowledge. It can optimize the teaching process and teaching methods, so as to improve the efficiency of classroom teaching, and then significantly improve the teaching effect.
