This research used a quantitative method to measure students’ understanding and interest in learning word problem by playing Jakri. Based on the level of RME approach, many students are able to reach level 1, students easy to accustom with Jakri game (real situation level), but students have some difficult to shifting from level 2 to level 3 (model-of level to model-for level). No one of them can reach the formal mathematics level (level 4). Students also have difficulty to do computation but the students create new mathematics sentence based on their own story.
