The purpose of this study is to diagnose student’s difficulties in learning about teorema pythagoras of VIIIFSMP Negeri 1 Amanuban Barat. The subjects consist of 17 student’s. The method that use in this study is qualitative with approach of case study.

The study revealed that student’s have less accuration in determining size of pictures and not able to make a conclusion. Based on students difficulties, to overcome those problems the researcher use the prosess of scaffolding to solve their problem in learning mathematics, such us: (1) asking student’s to find their difficulties in mathematic, (2) giving student’s oppourtunity to think logicaly, (3) giving some instruction questions in order to student’s are able to use the appropriate mathematics concept. (4) asking student’s to reflex their own answers to find their problem and difficulties.
