Aim of this study is about mathematics education and dynamic mathematics software. Dynamic mathematics software provides new opportunities for using both computer algebra system and dynamic geometry software. GeoGebra selected as dynamic mathematics software in this research. In this study, it is investigated that what is the usage of pre service mathematics teachers for teaching and learning mathematics concepts. Qualitative research methodologies were used in this study. First participants learned basic commands about GeoGebra. During lessons pre service teachers of mathematics used dynamic worksheets. Data were collected by participants' works and opinions on dynamic mathematics software. According to responses of participants, pre service teachers want to use dynamic mathematics software for teaching mathematical concepts. Their works on GeoGebra showed that participants want to offer interactive dynamic mathematics worksheets on internet to the students for mathematical concepts. (Contains 7 figures.)
