First, the use of electronic whiteboard, creating a problem situation Situational teaching is mainly a vivid image of the situation to stimulate students to learn emotional a teaching method. Problem situations can be familiar scenes of life for students, interesting mathematical activities or mathematical problems that need to be addressed. Traditional teaching passes the limited form such as the book to the student to transmit the information, can not arouse the student’s study interest well, the classroom teaching can not achieve the good result.
