The purpose of the research was to design a project of teaching spatial concept to help kindergartens to have spatial concept and learn to tell left and right before entering first grade. The method of the research was experimentation. The subjects of research included two classes of 5-6 years old kindergarteners. The experimental group accepted the teaching project which was an integrated instruction model. The control group adapted normal teaching method. The model design of the experimental group was basic on cross subjects teaching to improve children grow in spatial problems solving. As the result of the experimentation, we knew the project is practical and the group had developed competence in spatial orientation.
