Question 1

What is NCEA AS 91028 about?

Accepted Answer

You need to show you understand how tables, equations, and graphs are connected to each other. This means taking information from one form (like a table) and being able to describe it as an equation or draw it as a graph—and vice versa. You'll work with linear, quadratic, and simple exponential relationships.

Question 2

What do students need to do for AS 91028?

Accepted Answer

1. Make clear links between tables, equations, and graphs so that you can move information between these three forms 2. Show you know the correct math vocabulary and concepts related to relationships and patterns 3. Use correct mathematical notation and representations (numbers, symbols, graphs) to explain what you're doing 4. Demonstrate understanding by connecting different representations to show they describe the same relationship 5. Relate your findings back to the context of the problem or use proper mathematical language to explain your thinking

Question 3

What's the difference between Achieved, Merit, and Excellence for AS 91028?

Accepted Answer

Achieved: You successfully investigate relationships by making links between tables, equations and graphs, showing you know the relevant concepts and can communicate using appropriate representations. Merit: You demonstrate relational thinking by connecting different concepts and representations together, selecting logical steps to work through the problem, and explaining how your findings relate back to the context or using clear mathematical statements. Excellence: You use extended abstract thinking to devise your own strategy, identify which concepts are relevant to the context, develop a chain of logical reasoning that connects your steps together, and communicate mathematical insight with correct mathematical statements.

Question 4

What mistakes do students typically make in AS 91028?

Accepted Answer

1. Not making explicit connections between the three forms—for example, solving an equation but not explaining how it relates to the graph or table 2. Using mathematical language incorrectly or not using formal terminology when required to show conceptual understanding 3. Failing to relate findings back to the real-world context or not explaining mathematical reasoning with proper statements
