The aims of a study to teach mathematics in Mawng, an Australian Indigenous language, shifted from providing a foundation to enhance transferral to English to involving a language maintenance aspect. The study took place in a multilingual community. The roles of multiple Indigenous languages in a mathematics lesson are reported on. It is argued that the use of the multiple languages as resources in the mathematics class contribute to the reinforcing the political status of Mawng in the community, including as a language of formal education.
