Number sense

INVESTIGATING PROSPECTIVE ELEMENTARY TEACHERS’ NUMBER SENSE, THROUGH MENTAL COMPUTATION STRATEGIES

ABSTRACT

The purpose of this study was to explore the number sense of prospective elementary teachers, through a test demanding mental computations and estimation strategies. Eighty seven pre-service teachers from the Department of Primary Education participated in this study. Findings were analysed with quantitative methods. At the end of the research, prospective teachers’ number sense was found to be very low, not only in what concerns rational numbers, but even about the basics of decimal system and elementary numerical properties.
