High school geography review lessons often face the problem of difficult content integration. Taking the unit review of "Lithosphere and Landforms" as an example, this paper proposes three major strategies. First, sort out big concepts, break through the limitations of textbooks, explore knowledge connection points, and construct the unit knowledge structure. Second, create situations and design learning tasks with understanding big concepts as the core. Third, realize in-depth understanding of knowledge through knowledge transfer and application, and promote students' ability leap and literacy improvement.
