• Resumen

  • Two groups of third graders at Campbell Elementary School in Arlington, Virginia, investigated how to represent the fair sharing of chocolate bars when there are fewer chocolate bars than people who want to share them. This investigation occurred before any formal teaching of fractions, and it revealed student understanding of partitioning a whole into equal pieces, fractional language and notation, using fractions to represent division, and equivalent fractions.
