Learning mathematics must require innovation and renewal because there are still many students who have not reached the KKM score. Therefore, the researcher wants to make a breakthrough in learning activities in elementary schools by using image media in mathematics learning block material with the hope of maximizing student learning outcomes so that students can apply the material learned by them into their daily life. This hope, not too much, because of mathematics. Building room materials began to be taught to students since the fourth grade of elementary school, semester two. However, in grade IV, the building material that is taught is just building cubes and blocks. In class V, apart from building blocks and cubes, prism and pyramid shapes are also taught. So in this case the class V teacher continues the material that was taught in the previous class. The research method used in this research is classroom action research. While the results of the study showed the results of the tests (pretest and posttest), the learning outcomes of students in mathematics had an increase in each cycle. This can be seen from the average posttest score obtained between cycle I and cycle II has increased, namely, the average post-test score in cycle I is 72.86 and the average value of cycle II is 89.29, so it can be concluded that there is increasing learning outcomes in mathematics subjects using image media
