【Teaching Content】 Beijing Normal University version of the sixth grade. [Teaching process] First, create the situation, the introduction of a new lesson 1. Import conversation. Teacher: Students, a lot of mathematical knowledge comes from our lives. As long as we look carefully with a mathematical perspective, we will certainly find out. (Courseware to produce some object rotation) 2. Questioning the observation. Teacher: Thinking from a mathematical point of view, what did we find? 3. Reveal the issue. Teacher: Yes, these beautiful pictures are drawn from a continuous rotation of graphics. There are still many such pictures in our lives because they decorate our lives and enrich our lives.
