The question mark in the picture appears for the first time in the textbook, which can distinguish the known conditions and the desired problem, and can also inspire the students to put forward a mathematical problem according to the known conditions. Third, guide students to solve the problem according to the operational meaning of addition and subtraction . Before this content can be learned, students have initially understood the meaning of addition and subtraction
