digital whiteboard price in pakistan. ????interest is the best teacher. Mathematics itself is abstract and boring. Traditional classroom teaching is mainly spoken. Students will feel monotonous and boring in their study. In addition, students' age characteristics (poor self-control ability and easy distraction) are caused by a single traditional mathematics teaching method. Students' ability to innovate in mathematics is difficult to improve. The use of multimedia teaching technology has largely solved the difficulties in traditional teaching. For example, in the teaching of "Awareness of the Circle", I used the electronic whiteboard to design an animation: with the beautiful music, the three small animals respectively rolled the three different shapes of bicycle wheels from the starting point to compete. As a result, the bear who rolled the round wheel easily reached the finish line first, and the deer and the rolling square wheel bunny who rolled the oval wheel were still pushing hard... Then the text shows the question: "Why is the round wheel running fast and steady? Can it be replaced by a square or ellipse?" At this time I introduced the subject "Cognition of the Circle". Introducing the subject through interesting animations, on the one hand, fully stimulates the various senses of the students, and always has an attraction to the students' attention, so that the strong interest in mathematics learning is full of the whole classroom; on the other hand, it is necessary to think about learning new knowledge. Problems that motivate students to be proactive. In such a pleasant atmosphere, once students are interested, they will learn mathematics with confidence and achieve the transition from ??I want to learn?? to ??I want to learn??. .
