One of the things that concerns educators when teaching in the classroom is how to embed math concepts to students so that students can understand the lesson. So the students are not just enter a formula to resolve the problem but the student can use his understanding as logic to solve a problem. So that, educators need to conduct research on the management of class actions is good. From this post can be seen that students can understand mathematics concepts through their own discoveries, through sharing with friends so they can understand math concepts. This study brings an inspiration for me to be able to do something  that can make the learning better.
