Digit position value and scale: A teaching approach for 4th and 6th grade of elementary school

This paper presents two teaching approaches, those of digit place value and scale, for 4th and 6th grades of primary school using RhodeScript Theory tools such as problem-position construction, realistic mathematics, representations, ICT use and interdisciplinarity. More specifically, this paper aims to present the application of the above mathematical tools and their use in teaching practice, specifically in the assimilation of the above concepts, in order to improve students' performance, increase their participation, their interest and enhance collaboration among them. Moreover, the objectives that are attempted to be fulfilled through this project are to make the learners and teachers realize that learning the steps of solving exercises and problems related to the concepts of digit position value and scale can be achieved through experiential and interdisciplinary approaches, which will make the students solve them in a more constructive and profitable way.
