“Standard (2011)” after the enactment of the Qingdao version of the textbook has been fully revised. The following is a brief introduction to the major revision of the compulsory education textbook and mathematics third grade textbook (hereinafter referred to as the new textbook). First, pay attention to the infiltration of geometric intuitive thinking The new textbook in the understanding of mathematical concepts, understanding of mathematical algorithms, analysis of the quantitative relationship between the focus on the intuitive geometric infiltration. 1. Hands-on operation, understanding of mathematical concepts. The new textbook focuses on letting students go through the process of hands-on operation in the arrangement of the content of “mathematical concept”, and recognizes the concept of mathematics through intuitive perception of intuitive operation.
