Meanings for Fraction as Number - Measure by Exploring the Number Line

Abstract : Construction of meanings for fraction as number-measure is studied during the implementation of exploratory tasks concerning comparison and ordering of fractions as well as operations with fractions. 12-year-old students were working collaboratively in groups of two with software that combines graphical and symbolic notation of fractions represented as points on the number line. Fractions as points and segments, ordering fractions as part of kinesthetic activities and abstracting the scaling of the numerical unit on the number line are some of the meanings developed.
