In this paper we unpack epistemological aspects of language and mathematicspotentials embedded in the ”language as resource” discourse. We use researchliterature, policy, and interviews with a mathematics teacher and a multilingualstudent to illustrate the potentials and how they are realised in the material. Weidentified a ”lever potential” and ”one new whole” potential. To consider thepotentials in a nuanced way, we propose an analytical model which contributeswith theoretical conceptualizations that allows for grasping a relation betweenepistemologies of language and mathematics from the perspective of thelanguage as resource discourse
