Abstract

This study aims to improve the learning outcomes of students on subjects of mathematics in the subject matter of planar structures by using the Numbered Heads Together (NHT) model in class V of Public Primary School 026609 of South Binjai. The present study is a classroom action research (CAR). Subjects in this study were students in class V of Public Primary School 026609 of Binjai Selatan, as many as 1 class consisting of 35 students.
