To learn "The Image and Properties of a Function", we must let students draw the image of the relevant function through the "tracing method", and cannot directly tell the result.

Don't be afraid to spend time, only through the "tracing method" can you understand the image of the function and deepen the understanding of the definition of the function.
After tracing the image, guide the children to summarize the function image and its properties, and summarize the influence of k and b on the function image.
The ultimate goal is for students to be able to draw images of functions, including simple and accurate images.
I would like to share with you the handouts and coordinate paper.
