摘要：A development of fort defending game is used to provide a learning design based on the mathematical literacy, integrated with the primary school curriculum in Indonesia is K-13. The method applied is development research adapted from Nieveen. It has three proper stages; preliminary, prototyping and development stage. The preliminary stage is where the researcher determines what so stated as basic problems of design planning. Next, the prototyping stage is the two step where the developmental design of the game is constructed in accordance with the aims of mathematical literacy, integrated in the Indonesia curriculum, specifically in term of basic competence lists, learning design and group activity sheet. The result of the first stage is marked as Draft I, and being validated by the expert. The Draft II is produced from the final step, is the description of developed fort defending game based, aimed to improve mathematical literacy integrated into the Indonesia curriculum. This draft has also been validated and applied in the real life teaching of first grade students in primary school.
