Abstract
This paper presents an analysis of Grade 5 pupils' work with similarity, based on an adaptation of Brousseau's classical puzzle. My main interest is in investigating the pupils' language repertoire and mathematical strategies for expressing enlargement in a situation involving similar shapes. A crucial point is to identify elements of the language use that contribute to seeing enlargement to preserve similarity as a multiplicative situation.
