This research aimed to examine the application of two-valued and fuzzy logics teaching in better understanding the precise approximate concepts of chapter 4 of Sixth grade mathematics. Participants of this study were 30 Sixth grade mathematics students from an elementary school in Sari (a city in the north of Iran) in the academic year of 2013-2014. Data were collected by a research–made 40 item questionnaire with close answers. The obtained information was analyzed based on a pre- and post-test by a paired-samples t-test. The results showed that teaching of propositional logic really does have influence on students’ better understanding of the precise and approximate concept.

Keywords: Teaching, precise and approximate, sixth grade mathematics, two-valued and fuzzy logic
