Abstract: The background of this research is the low of Mathematics’ learning result in subject material the Lowest Common Multiple. Based on pre-cycle test result from 24 students, there are 20,83% reaching minimum criteria of mastery learning while 79,17% have not reached minimum criteria of mastery learning. This classroom action research aims to improve the activity and learning outcomes of grade IV of SD Negeri Maribaya 1 in Semester I of the academic year 2016-2017. The subject of this research is the students of grade IV with total number of 24 students. The method of data collection in this research is used tests, observation, documentation, and interviews. Based on the result of the research in subject material the Lowest Common Multiple has increased through the Fakel glass. The student activities from 5 indicators in the cycle I is average 77% (active category) being 92% in Cycle II (active category). The learning outcomes at the initial condition of class completeness is only 20.83% on average 53.75 increase cycle I reach 45.83% on average 69.58 and in cycle II to 75% with the average class 81.25. The conclusion of this research is the application of learning glass media Fakel can increase the activity and learning outcomes mathematics subject material the Lowest Common Multiple.
