Bobbie Hunter, Auckland University

Brief workshop overview: Being able to understand fractions as quantities is the central foundation for students being able to operate on fractional numbers with meaning. Bobbie will introduce an alternative way to develop understanding of fractions as quantities through the use of concrete materials called ‘Martian chocolate bars’. Through discussion we will also explore the important generalisations children need to construct when ordering fractions as well as how to use Martian chocolate bars to find fractions of a set.
