The design of this research was a quasi experimental. The population in this research were class VII SMP N 13 Pekanbaru. With purposive sampling technique was taken two classes of the population VII.5 class (class conventional) and VII.7 (experimental class) to serve as the research sample. Based on the results of tests of homogeneity of the final data obtained 𝐹ℎ𝑖𝑡𝑢𝑛𝑔= 1.53 and 𝐹𝑡𝑎𝑏𝑙𝑒 = 1.80 the values obtained 𝐹𝑐𝑜𝑢𝑛𝑡<𝐹𝑡𝑎𝑏𝑙𝑒 (1.53 <1.80). So it can be said that the two groups of samples have the same variance (homogeneous). Meanwhile, based on the results of the t-test values obtained right side 𝑡𝑐𝑜𝑢𝑛𝑡= 1.77 and 𝑡𝑡𝑎𝑏𝑙𝑒 = 1.67 with 𝑡𝑡𝑎𝑏𝑙𝑒 value dk = 69 and 𝛼 = 0.05, to obtain 𝑡𝑐𝑜𝑢𝑛𝑡> 𝑡𝑡𝑎𝑏𝑙𝑒 (1.77 > 1.67) then 𝐻𝑂 rejected, or it can be said that the mathematic learning outcomes of students in experimental classes are better than the control class. Further, the calculation result of the influence coefficients (Kp) was Kp = 4.3% . In other words, it can be concluded that the effect of the implementation of cooperative learning model Number Head Together
