NCEA L1 Maths case studies
NCEA L1 Maths · Put your knowledge to work in context.
NCEA Level 1 Mathematics and Statistics is the first of the three NCEA levels, and NCEA is described by NZQA as the main qualification for secondary school students in New Zealand. In general, students work through levels 1 to 3 in years 11 to 13 at school. Mathematics and Statistics splits into two connected strands: mathematics is the exploration and use of patterns and relationships in quantities, space, and time, while statistics is the exploration and use of patterns and relationships in data. Achievement in the subject is assessed through several standards, each covering a specific set of skills and knowledge, and each standard you achieve is worth credits towards the qualification. The NCEA L1 Maths case studies are 5 cases and about 3,038 words.
