The Theory of Primary Mathematics Teaching, edited by Fan Wengui, is a textbook for primary education majors in colleges and universities. Its main contents include: the professional development of primary school mathematics teachers, the objectives and contents of primary school mathematics curriculum, primary school mathematics learning theory, primary school mathematics teaching methods, primary school mathematics teaching design, primary school mathematics teaching means, number and algebra teaching, graphics and geometry teaching, statistics and probability teaching, comprehensive and practical teaching, primary school mathematics teaching evaluation and primary school mathematics education research methods.

The characteristics of "Theory of Mathematics Teaching in Primary Schools" are: first, paying attention to the professional development of primary school mathematics teachers, that is, taking the professional development of primary school mathematics teachers as the main line, reflecting a new round of basic education curriculum reform, so as to improve the education and teaching quality of normal students; The second is to combine the case teaching theory, that is, to closely connect with the reality of primary school mathematics teaching, highlight case teaching and pay attention to cultivating the primary school mathematics teaching ability of normal students; The third is to penetrate the development history of mathematics, that is, to briefly introduce the development history of numbers and algebra, graphics and geometry, statistics and probability, so as to enhance normal students' understanding of the development process of mathematics and thus develop a correct way of thinking in mathematics; The fourth is to infiltrate mathematical thinking methods, that is, to introduce mathematical thinking methods based on primary school mathematical knowledge, so that normal students can develop good mathematical quality.
