The Jigsaw learning model focuses on student activities in learning in general and also has an influence on students' mathematical abilities, but there are also some that do not have a significant influence. This research attempts to answer how much influence the Jigsaw model has based on the desired categorical variables. Therefore, meta-analysis research is needed to provide comprehensive and in-depth conclusions about the application of the Jigsaw model to students' mathematical abilities. Comprehensive Meta-Analysis (CMA) is used to evaluate a property's value based on comparisons to similar properties in the same area. Data was obtained from Publish or Perish (PoP) with a total of 500 articles from 2010 to 2023 with the Google Scholar database. The number of journals that meet the requirements and will be analyzed is 30 sample articles with a total of 1252 students. The moderator variables in this study consider country, education level, sample size and publication source. Based on research findings, the Jigsaw model has a significant influence on numeracy skills (P-value 0.05), with an effect size of 1.146 which is classified as very high based on fixed effects and a standard error of 0.045. The research results show that the Jigsaw model is still relevant for improving students' mathematical abilities, especially at the elementary school level. This meta-analysis study reveals that there is no difference in the results of implementing the Jigsaw model on students' mathematical abilities in all country categories.
