Penelitian ini bertujuan untuk mengetahui pengaruh model Numbered Head Together berbantu media puzzle terhadap hasil belajar ditinjau dari aktivitas belajar matematika siswa kelas IV SD Negeri 04 Loning. Jenis penelitian ini adalah Quasi Experimental Design. Subjek penelitian ini adalah siswa kelas IV. Untuk mengetahui pengaruh model numbered head together berbantu media puzzle dilakukan dengan menggunakan uji korelasi terhadap persepsi siswa tentang model numbered head together berbantu media puzzle dengan aktivitas belajar siswa, selain itu juga menggunakan uji t untuk mengetahui perbedaan hasil belajar siswa antara siswa yang aktivitasnya tinggi dengan siswa yang aktivitasnya rendah. Berdasarkan uji korelasi diperoleh rhitung > rtabel atau 0,658>0,396 sehingga H0 ditolak. Jadi ada korelasi antara persepsi siswa model numbered head together berbantu media puzzle dengan aktivitas belajar siswa dan uji regresi pengaruhnya sebesar 43,39%. Sedangkan hasil uji t sebesar  thitung =2,132 sedangkan ttabel=2,070 dengan t1-1/2 α dengan taraf signifikan sebesar 5%, sehingga –ttabel< thitung >ttabel atau –2,070< 2,132>2,070, dengan demikian H0 ditolak. Sehingga ada perbedaan hasil belajar antara siswa yang aktivitasnya tinggi dengan siswa yang aktivitasnya rendah pada pembelajaran matematika kelas IV SD Negeri 04 Loning.

This research was aimed to determine the effect of Numbered Head Together model assisted puzzle media on learning outcomes in terms of mathematics learning activities in case of fourth grade students. Trough Quasi Experimental Design. Subjects of this research were the fourth grade students of SD Negeri 04 Loning. To know the effect of model numbered head together assisted media puzzle done by using correlation test to student perception aboutnumbered head together model assisted puzzle media with student learning activity, besides also using t test to know different result of student learning between students with high activity and students with low activity. Based on the correlation test obtained rcount>rtable or 0,658>0,396 so that, H0 was refused. So concluded that there is a correlation between student perception numbered head together model assisted puzzle media with student learning activity and on regression testing  influence is 43,39%. While t test result is equal to tcount=2,132 while ttable=2,070 with t1-1/2 α with significant level equal to 5%, so – ttable<tcount>ttable or -2,070<2.132>2.070, thus H0 rejected. So, the result showed that there were differences on learning outcomes between students with high activity and students with low activity in learning mathematics of fourth grade SD Negeri 04 Loning.
