This study aims to present a mathematics teaching content aiming to support the teaching of slope for understanding slope conceptually in the classroom environment using computers and dynamic mathematics software. Within the scope of an implemented instructional sequence, the developed and also open to development steps of the activities integrated with GeoGebra files were evaluated so that eighth-graders can make sense of the slope concept in daily life situations. The findings revealed that the implementation of the instructional sequence prepared to explain the slope of a physical structure/object through activities integrated with GeoGebra files involving various situations on slope-related and non-slope related attributes offers a rich environment for mathematics teaching-learning. The findings also revealed that there may be some difficulties during implementation and how these difficulties can be overcome. As a result of the study, suggestions are made for future studies to be conducted on this topic.
Key words: Slope, dynamic mathematics software, computer assisted classroom environment, middle school mathematics curriculum
