l smart board. [Abstract] With the rapid development of modern educational technology, electronic whiteboard assisted teaching has entered the mathematics classroom. Using interactive whiteboards, digital and visual combination can be achieved, which provides a favorable platform for teachers and students to interact, helping students master the content of mathematics teaching, combining "static and dynamic" to students. The process of generating knowledge can not only improve learning efficiency but also make it easy to learn. It provides a rare tool for teachers to optimize mathematics classroom teaching. Only by giving full play to its advantages and getting out of the misunderstanding can we combine the traditional teaching methods with the advanced electronic whiteboard assisted teaching in order to create an efficient and pragmatic mathematics classroom and achieve the goal of getting twice the result with half the effort.
