The purpose of this study is to reinterpret the Teaching Games for Understanding (TGfU) as a curriculum theory and to explore its values and limitations. Accordingly, the beginnings and transitions of TGfU were explored, and the philosophical, pedagogical, and psychological basis underlying this theory were examined. Based on this, the main concepts of this theory were rearranged and reinterpreted in the framework of objective-content- method-assessment. The contents are as follows: 1) Objective: to develop the ability to solve common problems in each game category. 2) Content: an existing or created game suitable for teaching the characteristics of each game category. 3) Method: develop and use tasks, including tactical problems. 4) Assessment: an assessment of performance in a practical context that can assess tactical understanding. As a curriculum theory, the value of understanding-based game lessons is as follows; 1) Present the criteria for the teacher curriculum. 2) Match physical education to the general values of education. 3) Enrich holistic interpretation to justify physical education subject. However, as a curriculum, TGfU has a clear limit in that it deepens confrontation with technique approach and is not suitable in all situations.
