Mathematics is an important subject for students especially in information age, but it is also a difficult subject in basic education because of its abstractness. "Solving math problems without ideas" is a common problem for many students. This study attempts to depict the visual design like simulation graphics and structure charts, which is theoretically feasible, to help students understand and apply mathematical concepts to solve math problems. Through the observation and evaluation in action research, it is found that the simulation graphics and structure chart are effective in math problem solving. Structure chart helps students understand the relationships between objects and qualitative relations in math problems clearly; imitation graphics can assist students to understand the context and concepts better when technical conditions are ready for use. The study results prove that the reasonable design and application of diagram in teaching can help students understand and grasp mathematical knowledge, and enhance their skills to use them in math problem solving. The study also finds that classified problems and modeling problem solving are feasible ways to help students to obtain and apply mathematical concepts and grasp how to use the problem solving model.
