This study developed teaching materials of life application simulation animations, and introduced the concept of trigonometric functions into actual stories to create animations. This study took the famous ancient Chinese mathematical measurement book, Hai Dao Suan Jing for example, and created 3D simulation animations, auxiliary lines, and graphics. It is expected to help students to understand the allusions and mathematical formulas of Hai Dao Suan Jing, and learn to use their height, change of location, and change of related projection to measure the height and distance of objects on the ground. By watching 3D simulation animations, students can better understand the mathematics questions through dynamic visualization, learn the principles of surveying, and learn the spatial conception of trigonometric functions. The use of teaching with computer animations to attract students’ curiosity regarding the application of mathematics to life can improve their imagination about surveying and simulation of spatial concepts.
