The aim of this study is determination of opinions of the math teachers concerning the learning environment that they design. In accordance with this aim, an opinion form which is comprised of open-ended questions is applied on 30 math teachers who are in charge in Middle Anatolian Region in Turkey. The data which are obtained as result of the application have been analysed and presented by using frequencies and percentages. It is understood from the obtained results that teachers benefit from the textbooks and auxiliary test books for designing the teaching environment, and they don't often give a place to different teaching methods and techniques.
