Historical maps can reveal historical details, clarify historical processes, help students establish a macro perspective, cultivate historical awareness and a sense of historical context, and contribute to the formation of core competencies in history. In middle and high school history courses, ancient Chinese history primarily focuses on documenting the changes of dynasties throughout history, with war history occupying a significant position. Integrating historical maps into the teaching of ancient Chinese war history is crucial for cultivating students' sense of time and space and forming historical thinking. Using historical maps for teaching involves more than just presenting maps; it requires careful identification and revision based on historical facts. The recognition of historical maps should follow the integrity of map content, pay attention to map titles, clarify map elements, and emphasize the comparison between ancient and modern times. The use of historical maps should adopt a combination of graphics and text, guiding students to observe or encouraging teachers and students to explore together, with a focus on the "dynamic" content expressed by war. Teachers should utilize modern information technology to obtain teaching resources from various sources and innovate the display mode of historical maps.
