Level 8 optimisation and data analysis learning programme example
- The following learning programme example is divided into three terms of work. Each term has an overarching mathematics focus to support the learning.
- Possible teaching and learning activities are given, from which teachers could select activities that best meet the needs of the students in their class/school. In addition teachers could select teaching and learning activities that they currently use, or source others that would meet student needs and address the focus.
- Each term has a list of possible achievement objectives to select from, the choice of which will depend on the selected teaching and learning activities.
- The intent is to be more holistic in the selection of achievement objects to allow for natural connections between and within strands.
- Some achievement objectives could be summatively assessed directly through achievement standards; others could be assessed through in-class formative or summative assessment. Not all achievement objectives need to be assessed.
Term 1 – Data analysis
Data analysis focuses on the presentation of data using appropriate table and graphs and modelling trends with linear (and non-linear) models. This is extended by using these to make calculations and continues by considering the appropriateness of the models and how they might be used.
Ideas for teaching and learning activities
-
Practical statistics:
- Samples (pp. 121-132)
- Estimating Proportions (pp. 133- 144)
- Estimation: Sampling Distributions and Point Estimates (pp. 145-163)
- Correlation (pp. 212-233)
- Linear Regression (pp. 234-253)
- Practical Investigations and Longer Projects (pp. 311-322)
Suggested achievement objectives
Select from below depending on the teaching and learning activities chosen.
Statistical investigation
- S8-1 Carry out investigations of phenomena, using the statistical inquiry cycle:
- A – conducting experiments using experimental design principles, conducting surveys, and using existing data sets
- B – finding, using, and assessing appropriate models (including linear regression for bivariate data and additive models for time-series data), seeking explanations, and making predictions
- C – using informed contextual knowledge, exploratory data analysis, and statistical inference
- D – communicating findings and evaluating all stages of the cycle
- S8-2 Make inferences from surveys and experiments:
- A – determining estimates and confidence intervals for means, proportions, and differences, recognising the relevance of the central limit theorem
- B – using methods such as resampling or randomisation to assess the strength of evidence
Statistical literacy
- S8-3 Evaluate a wide range of statistically based reports, including surveys and polls, experiments, and observational studies:
- A – critiquing causal-relationship claims
- B – interpreting margins of error

Term 2 - Optimisation
Optimisation focuses on the use of linear equations, inequations and networks to optimise situations and processes.
Ideas for teaching and learning activities
-
Co-operative mathematics for level 8:
- Mix and match activities
- Simultaneous equations with inconsistent solutions (p. 6)
- Information-sharing activities
- Simultaneous equations (q. 22, 23)
- Double sequencing activities
- Simultaneous equations (p. 39)
- Linear programming (p. 41)
- Possible context elaborations for
AO M8-4
- Possible context elaborations for
AO M8-5
- Possible context elaborations for
AO M8-8
Suggested achievement objectives
Select from below depending on the teaching and learning activities chosen.
Patterns and relationships
- M8-4 Use linear programming techniques
- M8-5 Develop network diagrams to find optimal solutions, including critical paths
Equations and expressions
- M8-8 Form and use systems of simultaneous equations, including three linear equations and three variables, and interpret the solutions in context

Term 3 – Experiments and statistical literacy
This term focuses on the development of statistical thinking and reasoning through experiments, statistical literacy and evaluation of statistical reports.
Ideas for teaching and learning activities
- Possible context elaborations for
AO S8-1

AO S8-2
- Possible context elaborations for
AO S8-3

Possible assessment programme
It is envisaged that this course could lead to assessment for a wide range of achievement standards enabling teachers to select appropriate assessment programme to suit individual students within the class/school.
