Mathematics teachers are required not only to transfer knowledge to learners but also to shape and develop the character of students in the learning process of mathematics. To be able to grow and develop the character of students required a model of learning that can bring the character formation indicators in the learning process. The learning model that can generate character development indicators is a Think-Pairs-Share (TPS) model of learning.
