A Case Study on the Use of Dual Numerals by Multi-Cultural Students in the 1st Grade of Elementary School

The purpose of this study was to analyze the characteristics of the use of dual numerals by multicultural first-grade students with linguistic characteristics and to provide basic data for establishing effective teaching and learning methods of the numeration. Accordingly, a case study was conducted to compare and analyze the characteristics that appear in the process of the use of dual numerals by multicultural students. Linguistic characteristics and the proficiency of using classifiers linked to individual numbers can affect learners' use of dual numerals. Both multicultural and non-multicultural students had difficulty using native numerals that used irregular naming systems. And they exhibited many different types of errors in different types using dual numerals. The results of this study can provide basic data for teaching dual numeral naming systems and can contribute to the establishment of effective teaching methods for numeration.
