This study aims to improve mathematics learning outcomes through cooperative learning type TAI (Team Assisted Individualization) in fifth grade students of SD Muhammadiyah 4 Tangerang City. This research was conducted on 30 students consisting of 14 male students and 16 female students. The learning used in this research is classroom action research using the spiral model of Kemmis and Mc Taggart.
