This is called Mini Book. For each chapter, the teacher requires students to make a mini book. The mini book is easy to make. By folding and cutting a line paper, an convenient "book" is done. Inside the mini book, students need to denote the key formulas or equations for the chapter. Every concept in math is derived from formulas. By making a mini book, students have a greater impression on the concepts.
This is our daily homework assignment. For each section in one chapter, students need to do the exercises after the lessen. Every mathematical person admits that practice is most significant to new concepts. By doing the questions, we can strengthen the lessons in our brains. Furthermore, the practice questions can also be used when we study for the tests or quizzes. They can refresh our knowledge of the concepts.
