Abstract

This study aims to determine the level of students algebraic reasoning mathematics learning in elementary school. This type of research is qualitative research. The subjects 3 students was fifth grade students of elementary school in Purworejo. The selection of subjects techniques in this study is snowball. Data collection uses learning activities with supporting media in the form of student worksheets, observation sheets, field notes and interviews. Data analysis techniques used from Miles & Hubermen which include three activities namely data reduction, data presentation, and conclusion drawing.
