knots geometry and its training in school

Euclidean geometry has been taught to students in schools for many years. Topological structures are among the topics that have not received much attention in school geometry. The knot is one of the most suitable topics for teaching in school, which has a topological structure. In addition to being rooted in human culture and experience, knots are a theoretical and practical field in mathematics, physics, biology, and chemistry. In this article, after a brief acquaintance with the nodes, an explanation for the title "Geometry of nodes" is given. In the first part of the article, in the first part, the reasons and analyzes for the selection of nodes and the importance of teaching it in school are explained, and in the second part, a proposed plan for teaching knot geometry to students is briefly presented. Experimental implementation of this project, in which one group of elementary school students and the other group including students from the third year of middle school and the first year of high school participated, has had satisfactory initial results.
