Problems solved by technology

[0002] In mathematics teaching, due to the needs of the course, the teacher often needs to draw pictures on the blackboard. By drawing pictures, students can understand the solution of the problem more intuitively. Drawing different figures often requires different teaching aids. The traditional teaching volume Large, large quantity, inconvenient to carry, it is quite inconvenient for the teacher to change the drawing utensils frequently when using it, and it will affect the teaching efficiency
