The Compulsory Education Mathematics Curriculum Standard (2011 Edition) regards “synthesis and practice” as one of the contents of the course, and proposes that “comprehensiveness and practice” is a type of learning activity that takes question as its carrier and student’s participation as the basis. In the background of a middle school entrance exam in Anhui province in 2012, this course through the students’ active observation, experiment, exploration, conjecture, verification, exchange and other mathematical activities, experiencing the thinking process of problem solving, cultivating the ability of discovering problems, asking questions and accumulating experience of mathematics activities , Forming an understanding of mathematical knowledge.
