This study aims to determine the ability of communication mathematics students in grade VIII SMP IT Suhadah Yogyakarta through cooperative learning type Number Head Together (NHT). This study is a classroom action research. The instrument used to collect data is a test instrument. The results of the research for the students' communication ability aspects improved from cycle I of cycle II for each aspect: the first aspect is illustrating mathematical ideas from 30% to 47%, an increase of 17%. The second aspect describes the answer and the use of symbols from 20% to 40.5%. The increase is as much as 20.5%. The total achievement for cycle II is 85.7%, which in this case has reached the criteria 85.7%> 85%. We conclude that NHT learning has been effective for students' mathematical communication skills on straight-line equations. In addition, for teacher and student activity, in the first cycle only active categories have increased
