Teaching content: PEP “compulsory education textbooks · Mathematics” fifth grade on the total review “from the mathematical thinking to the gradual transition of algebraic thinking.” Teaching Objectives: 1. Will use letters instead of numbers to calculate, can contain the letters of the formula summed up the same rules, letters can be used to represent unknown, so as to create the conditions to solve the problem. In the process of solving problems, we can understand the difference and characteristics of arithmetic thinking and algebraic thinking, and perceive the unique function and value of algebraic thinking method. 3. Development of independent thinking and team cooperation and exchange
