It also helps to find out the status of students' participation in classroom activities and to create a mathematical classroom full of inquiry, cooperation and harmony. In the teaching of Beijing Normal University version of the second grade of mathematics on the third unit of the second class “observation object” take a look (b) after. Reflections on teaching presupposition and process, I have a few feelings I would like to share with you: First, respect for students' cognitive activities to create classrooms
