This assessment is about students demonstrating that they can use a variety of mathematical methods to solve abstract and real world problems.
The following page covers each of these skills and how to sit the assessment.
This standard is assessed as an exam at the end of the year.
Students must complete the questions independently under test conditions.
The test involves three questions each with 4-5 sub-parts. Some of these sub-parts require multiple skills.
Expected proportion of each grade in this standard is approximately:
Not Achieved: 35% of students
Achieved: 30% of students
Merit: 25% of students
Excellence: 10% of students
The teacher cannot provide any assistance.
All work must be completed by the student during the assessment.
This standard requires students to:
use mathematical methods including:
Number and Algebra
manipulating and simplifying expressions
generalising properties of numbers and operations
inequations
linear and quadratic equations
simultaneous linear equations with two unknowns
optimal solutions
relate graphs, tables, equations, and patterns
relate rate of change to the gradient of a graph
Measurement, and Geometry and Space
Pythagoras’ theorem in right-angled triangles in 2D and 3D situations
trigonometric ratios in right-angled triangles in 2D and 3D situations
properties of similar shapes
surface area of prisms, pyramids, cones, and spheres
volume of pyramids, cones, spheres, and composite shapes including prisms
use mathematical concepts and terms
communicate using appropriate representations (equations, symbols, graphs, sentences)
carry out multiple steps correctly with a clear chain of reasoning
form a generalisation
complete a proof

Ensure you have a strong knowledge of the Number, Algebra, Measurement, and Space parts of Junior Mathematics.
Students should be familiar with the formulas shown in this sheet.
This is the formula sheet for NCEA Level 1 Maths 1.4 and shows the kinds of formulae available to use in this exam.
These formulas include those for Perimeter (Circumference) and Area, for Circles, Triangles, Quadrilaterals, those for Surface Area and Volume of Prisms, Cylinders, Spheres, Pyramids, Cones, and Rectangles, along with Pythagoras' Theorem, the Trigonometry Formulas (SOH CAH TOA), and some simple unit conversions.
The following are past assessments along with their marking schemes and student answers for 1.4 Mathematical Reasoning.
The website snedmaths made by Maths Teacher Mr James Sneddon, Head of Mathematics at Saint Kentigern College, has made a bunch of extra practice papers formatted in the same way as the past papers.
These are really good to practice with.
Take a look at them by going to the snedmaths Google Site.
