Students' numeracy skills are still relatively low. This can be seen when many students in their multiplication test have not answered the questions given and this is because students still do not understand the concept of multiplication. which is set. The purpose of this study is to Improve Students' Numeracy Skills Through the Jarimatika Method of Class III UPT SPF SD Inpres Minasa Upa Makassar City. This study was conducted with classroom action research (PTK). The subjects of the study were 19 students of class III UPT SPF SD Inpres Minasa Upa Makassar City. Data collection techniques were observation, testing (evaluation) and documentation. The data obtained were analyzed using quantitative and qualitative descriptive analysis.
