Research on the Current Situation of the Combination of Numbers and Shapes in the Middle School of a Primary School in Changsha City

The revision of the Compulsory Education Mathematics Curriculum Standards (2011 Edition) adds arithmetic ability, model thinking innovation consciousness, and geometric intuition to the six core vocabulary in the original curriculum standard, such as number sense, symbol sense, spatial concept, statistical concept, application consciousness, and reasoning ability, and puts forward clear requirements for the combination of numbers and shapes. Abstract truths are important, but they should be seen and felt by students, especially for those in the lower grades of primary school. The combination of numbers and shapes is a good method, which is not only a problem-solving method but also a mathematical idea in intuitive abstraction, which runs through the whole mathematics learning career of students. Based on this, this study focuses on the primary school mathematics classroom, focuses on the implementation of the combination of numbers and shapes, and uses the literature method, questionnaire method and observation method to find the problems in the combination of numbers and shapes in the lower primary schools, analyze the causes of the problems, and put forward improvement strategies.
