The purpose of this article is to synthesize and analyse the most frequently occurring, widely dispersed and pedagogically useful lexical bundles in mathematical texts. Drawing on a five-million-word corpus of graduate-level textbooks, a total of 65 academic sequences meeting a predefined set of length, frequency and distribution criteria are…
