“Application” is the second phase of Shanghai City Mathematics curriculum teaching content. Application problems for second-year students is a certain degree of difficulty, how to enable students to correct questions, understand the meaning of the problem, looking for the necessary conditions for column calculation is that our teachers need to overcome a difficult time. This lesson is after students learn the three-digit addition and subtraction application questions, further study by multiplication and addition of mixed application questions. The purpose is to train students to find out the hidden conditions in the subject according to their life experiences, to correctly solve the multiplication and multiplication problems, and to cultivate students’ thinking ability and problem-solving ability by solving the open application questions.
