Abstract This paper takes the use of different numbers of plastics in the plastic recycling sign in life as the carrier, and assists the self-made teaching aids to carry out model splicing. In the component analysis of plastics corresponding to different numbers in the plastic recycling sign, it not only implements the basic methods of synthesizing polymers and the application of polymer compounds in life, but also cultivates the students’ academic literacy of macro identification and micro discrimination.
