Abstract

An integer counting operation is one of several basic materials in mathematics learning whose applications are used up to college. This shows the importance of understanding counting operations on integers. This study aims to improve student learning achievement in integer counting operation material through the use of number line props. This research is a classroom action research with 3 cycles, in which the research subjects are students of class VII B SMP Negeri 9 Jambi City. The results of the study showed the enthusiasm of students in participating in the learning starting from the first, second and third cycles had increased.
