I study math, so I said that math and math handwritten newspapers are easy to get. You can draw a pie on your picture (that is, 3. 14 15926 ...) and divide the whole picture into four sections. You can write a title (theme) on it, such as how to learn math well, and then fill in the following three sections respectively. For example: 1. Talk to students who are good at math. 2. Write down some mathematical laws or skills that some students may not know. 3. Find some paragraphs and short messages about mathematics, such as how to express the pursuit of love of mathematics students, and be sure to use mathematical symbols.
