<![CDATA[The lack of numeracy knowledge among students at State Elementary School 013 Kaliamanting Island Village is a problem so further learning is needed The aim of this research was to assess the impact of using the Jarimatika method on students' multiplication abilities in classes V and VI of the Kalimanting Island State Elementary School. This research focuses on the application of Jarimatika as a tool in solving multiplication problems. The motivation for this research arose because students did not have adequate skills in dealing with multiplication, and monotonous teaching methods made learning mathematics difficult. The method used in this research is an experiment with a quasi-experimental design known as a nonequivalent control group design. The experimental group was treated with the Jarimatika method, while the control group continued to use conventional methods which included expository, question and answer and rote memorization methods. Data was collected through tests, and research results were analyzed using descriptive statistical techniques. The research results showed an increase in the average score on the pretest and posttest. From the test results, it can be seen that there is a different increase between the control group and the experimental group. The increase in the average score in the control group was 19 points, increasing from 52 to 71, while the experimental group experienced an increase of 22 points, increasing from 54 to 76. Also, the increase in multiplication calculation ability in the control group was lower than in the experimental group. These findings show that the use of the Jarimatika method has more impact on the multiplication abilities of class VI students in elementary school]]>
