Abstract

Specialist Studies in Education
This paper presents a case study of one primary school teacher's journey of realisation about the importance of proportional reasoning for numeracy. Through immersing students in a rich numeracy investigation to meaningfully compare the world's tallest mountains, this teacher reflects on authentic contexts and hands-on experiences for promoting and enhancing students' multiplicative thinking. This study included analysis of interview data, classroom observations and student artefacts against a rich model of numeracy that served to emphasise the power of meaningful contexts for promoting multiplicative comparison.
