NCEA Level 2 Maths - 2.5 Networks Standard A/M/E Guide
This 91260 (2.5) standard is worth 2 credits and contributes to your Level 1 Numeracy requirement.
In this standard, the numerical units you will be likely to use are not limited to; distance (length) but also cost and scenery rating.
You are very likely to be given a real life issue / mathematical context in your test rather than a simple ย question. Such as; you might be given a route of major roads in Auckland / Hawkes Bay cycleways, or anything like that.
For an Achieved, you need to correctly calculate the minimum and maximum values and also determine correctly whether the network for this case study is traversable or not. Also you need to show drawings and some brief descriptions. Make sure your communication is also clear.
For a Merit, you need to describe why/why not the network is traversable and also describe how you found shortest/longest routes (what methods?), etc. And also you need to be able to decide by yourself which route would you like to keep/remove to cater for groups of people's needs and explain why. And sum up the total length/cost/etc. It's up to you to decide but you need to support your decision with specific evidence relating to costs/distance etc and which groups will/won't it serve, etc.. (hope that makes sense)
And for an Excellence, you need to: - Devise a new strategy - merge all features into one tree. For example, let's assume you've got 3 separate networks (each showing length, time taken and scenic rating). you gotta condense them into one. There would be lots of decision making so I'd strongly recommend you plan first. Decide wisely though which route do you wanna keep and which one do you not want to have. You also need to justify why and how would this decision affect groups of people. You also gotta say whether your new strategy would be traversable or not (and why?) And you could also talk about improvements (what can be better?).
I guess that's what you gotta do for this internal. Contact me anytime if you have any queries. Your feedbacks and suggestions will also be greatly appreciated.ย
