DESIGNING AND USING REALISTIC MATHEMATICAL PROBLEMS IN TEACHING NATURAL NUMBERS AND CALCULATIONS WITH NATURAL NUMBERS FOR VIETNAMESE ELEMENTARY SCHOOL STUDENTS

Mathematics has more and more applications in real life. The 2018 General Education Mathematics Program of Vietnam not only provides students with knowledge and skills but also creates opportunities for students to apply mathematics to solve practical problems accurately and flexibly. Therefore, in teaching Mathematics in general, teaching Natural Numbers and calculations with natural numbers in primary school in particular, it is necessary to create opportunities for students to apply mathematical knowledge and skills to solve practical situations. This paper proposes a process for designing and using practical problems in teaching Natural Numbers and calculations with natural numbers for primary school students in Vietnam. At the same time, the article provides an example to illustrate the proposed process.
