Solving a Linear Optimization Word Problems by Using GeoGebra

Abstract Today's modern age is characterized by the rapid development of information and communication technologies, which is also reflected in the educational process. It is therefore necessary to prepare the young generation of even at primary and secondary schools to solve problems from real life. Using the appropriate motivation, innovative methods and application of modern information and communication technologies into the teaching process, we can succeed. Constructions created using by dynamic geometry systems bring new opportunities to learning. The aim of this article is to introduce the possibility of using GeoGebra in graphics solution of system of linear inequalities and also in the geometric interpretation of solutions to word problems leading to the linear optimization. The article describes the observations of experimental teaching, where was used GeoGebra. The experimental teaching was conducted at a grammar school in Košice. GeoGebra offers suitable tools to create graphical models in solving the optimization problems.
