<![CDATA[Diversity of characters, different levels of learning understanding and difficulties in understanding learning concepts make it difficult for teachers in the teaching and learning process because students are still unfamiliar with the material so that teachers are allowed to provide a real picture so that the learning material is easily understood by students. The learning process requires a learning model that can make students learn optimally by using a cooperative learning model, one of which is the Team Assisted Individualization (TAI) model. The use of learning media that brings students closer to everyday experiences about mathematical concepts realistically by using an experiential approach to real-world situations or concrete objects. The purpose of this study was to determine the application of the Team Assisted Individualization (TAI) learning model using concrete object media to improve students' ability to understand mathematical concepts in angle material. Based on the literacy results obtained from seven relevant journals regarding "Analysis of the Application of the TAI Model Assisted by Concrete Media on Understanding the Mathematical Concepts of Angle Material" it was found that learning the concept of angles with the aid of concrete media using the Team Assisted Individualization (TAI) cooperative learning model can have a positive effect on learning process and improving student learning outcomes so that it can be applied to elementary school level mathematics learning]]>
