Indigenous language speaking students in remote Northern Territory schools are expected
to learn mathematics in English and are assessed in English. Most teachers in these schools
have little knowledge of the mathematical concepts with which their students start school.
This paper reports on the initial findings of a project which is investigating spatial concepts
in Iwaidja, an Indigenous language spoken in the NT. Examples of spatial frame of
reference preferences in Iwaidja and related languages are compared with those taken for
granted by English speakers. Implications for mathematics teaching are explored in the
context of an Australian Curriculum
