The paper reports some findings about how pre-service students engage with the mathematics and statistics section of the "New Zealand Curriculum" (2007), when writing a yearly long-term plan in this curriculum area. This authentic task for pre-service students provided opportunities to seek out information about relevant curriculum knowledge including reviewing and revising mathematical content. This paper is part of a larger study, which focuses on the needs and concerns of final year primary pre-service teachers as they anticipate teaching mathematics in their first year of teaching.
