Currently, there is much dynamic math software. They help to provide the user with an intuitive mathematical environment. Also, thanks to the dynamic properties of the software, users can flexibly change mathematical forms and objects by pressing and dragging. Therefore, they have multiple opportunities for surveying, predicting, illustrating, or finding strategies for solving mathematical problems. GeoGebra software is used in this study to find strategies for solving a problem, as GeoGebra integrates and serves many math disciplines. Concerning the math studies solving a problem with GeoGebra's support, this paper devotes particular attention to using Polya's four-step process to a problem. It is a generalized scheme that can be applied to find solutions for all kinds of mathematics. The issue is how to exploit the strength of this dynamic math software if we use this scheme to find strategies for solving a problem. Our research content is to answer the questions: 1) How do students approach solving a math problem with the GeoGebra software? 2) What students' mistakes or limitations can occur? Experimental research results with six student groups have shown that students have made some mistakes with GeoGebra in math problems and they do not know how to take advantage of this software to make it easier to find a solution to the problem. Based on the findings, we suggest several measures to show teachers and students how GeoGebra is used effectively.
