This study focuses on the use of mathematics learning media in improving the students' defense and interest in learning pythagoras theorem. Research subjects taken in one school in Bima City West Nusa Tenggara Indonesia. Research sample were taken randomly/ randomly to follow the learning by using manipulative media. Learning media designed in the study there are two, namely ICT and Non ICT media.
