Abstract
The aim of this study is to design learning activities that can support students to develop strategies for the addition of number 1 to 20 in first grade by involving students? spatial structuring ability. There are three activities that have been conducted in this study, namely dice games, rubber ball box activity, ten-box activity. In this paper, one of three activities is discussed namely rubber ball box activity. The aim of this activity is to introduce and develop double-structure to be a students? strategy in addition of number 1 to 20. PMRI underlie the context and activity. The method used in this study is design research through three steps namely preliminary design, teaching experiment and retrospective analysis. This study was conducted in SD Negeri 179 Palembang as a partner school of PMRI by involving 27 students of Grade 1. The result of the study indicates that rubber ball box activity can help students to develop double-structure as a strategy in addition of number 1 to 20. Based on the learning activities, students can develop and use spatial structures to develop their strategies, either using double structure as strategy to determine the number of structured balls or unstructured balls. Students can explore their strategies in solving problem of addition of number 1 to 20. As a recommendation, PMRI can be implemented as an approach of teaching and learning addition 1 to 20
