This study focuses on: whether there is an effect of small group work learning strategies on thematic learning outcomes and how much influence small group work learning strategies have on thematic learning outcomes of class V SDNU Bangil students. This research method uses quantitative correlation with data collation techniques through questionnaires, observations, interviews, and documentation and data analysis using product moment correlation statistics. From the results of this study indicate that the learning strategy of small group work on thematic learning outcomes of class V SDNU Bangil students has no effect that before the small group work learning strategy was carried out, 30% grade V students did not achieve the Minimum Completeness Criteria (KKM), while after 32% implementation of small group work learning strategies that did not reach the KKM. As the results of the data analysis obtained that first, there is no effect of small group work learning strategies on thematic learning outcomes of class V SDNU Bangil students, this is evidenced by the value of statistical data results which show that "r" work (ie 0.26) is more the size of the "r" product moment table where N = 28 in the 95% confidence interval is 0.374 and in the 99% confidence interval a value of 0.478 is obtained, it can be said that there is no influence between variable X and variable Y. Thus the working hypothesis the writer used stated that there was no effect of small group work learning strategies on thematic learning outcomes of class V SDNU Bangil students "not accepted". Second, the influence of small group work learning strategies on thematic learning outcomes of class V SDNU Bangil students is low. This is evidenced by the results of statistical data analysis which shows that the "r" of work is 0.26 in the coefficient interval 0.20 - 0.399.
