What is a Maths Investigation?What is a Maths Investigation?
An investigation may be defined as“a situation originating in mathematics or the
real world which lends itself to inquiry.”
Inquiry ---making observations, asking questions and pursuing
investigations has always been a fundamental approach to
understanding the world.
A mathematics investigation allows students to examine situations using various techniques and in the process of their exploration develop skills that can be applied to other problems.

Why do a Mathematics Why do a Mathematics Investigation?Investigation?
It caters for student diversity and investigative work is viewed as a key way to engage and motivate learners.
Students need to formulate their own questions from a given situation.
By formulating their own questions, students give teachers a clear indication of their level of knowledge and/or understanding of the topic.
It requires students to use mathematical processes to understand the problem or situation.
First hand data – generated by the student is much better for learning than second hand data!
Students develop a systematic record of their work not only an end product.

Aims for students to ‘recognise connections between the areas of mathematics and other disciplines and appreciate mathematics as an accessible and enjoyable discipline to study.’
Students need to recognise that mathematics is constantly used outside the mathematics classroom and that numerate people apply mathematical skills in a wide range of familiar and unfamiliar situations.
Using mathematical skills across the curriculum both enriches the study of other learning areas and contributes to the development of a broader and deeper understanding of numeracy.

Mathematics is organised around the interaction of three content strands and four proficiency strands.
The proficiencies reinforce the significance of working mathematically within the content and describe how the content is explored or developed.
‘The curriculum anticipates that schools will ensure all students benefit from access to the power of mathematical reasoning and learn to apply their mathematical understanding creatively and efficiently…..’ ‘It encourages teachers to help students become self-motivated, confident learners through inquiry and active participation in challenging and engaging experiences.’

The AusVELS Domains
Thinking ProcessesThinking Processes
The type of skills normally associated with investigations are generally higher order skills or processes.
• These processes fall under the broad heading of Working Mathematically-
The Australian Curriculum proficiencies reinforce the significance of working
mathematically within the content and describe how the content is explored or
developed.• Thinking Processes- AusVELS Domain – students will be developing
creative and critical thinking abilities, and applying them to the expansion of their knowledge and skills.
• “We are preparing students for an uncertain future, there will be problems to solve that probably don’t yet exist.”
• The aim of developing thinking skills through the investigation process is - to provide students with the ability to apply and transfer knowledge to
new and different circumstances as they arise throughout life - to understand and act effectively in the ever changing world in which they
live.Back to Index

Getting Started.Getting Started.
Be Creative and Individual.Choose something that interests you.
Use: Mind mapping Brainstorming Lateral thinking
Begin: Brainstorm Ideas and Inspiration for Investigation. Begin a Log or Journal Clearly Explaining the Investigation, Thinking
and Learning Processes and Understandings. Generate Ideas for Topic and Related Mathematical Content. Select Topic and Outline Investigation Content. Ensure Acquisition and Management of Resources. Develop a Timeline. Consider Presentation Format. ( Posters, Booklets, Display Folders, ICT/CD and Support Materials such
as Models are all acceptable. Models must relate to the mathematics not just be an artistic display “add on”.)

Investigation StepsInvestigation StepsInvestigation Aim:
A question is a problem if the procedure or method of solution is not immediately known to you but requires you to apply creativity and previous knowledge in new and unfamiliar situations.
If the procedure or solution is obvious then it is not a problem but an exercise.

Questions. Reflections. Explain or Justify Results. Test Conjectures. (Use strategies) Make Conjectures. (Formation of opinion on incomplete grounds.) Explore Systematically. (Use strategies) Get to Know the Situation and Formulate Questions. Define your AIM. Choose your TOPIC.Begin Log or Journal.

A Learning JourneyA Learning Journey
“Mathematics is not a careful march down a well-cleared highway, but a journey into a strange wilderness, where the explorers often get lost
and discover more than they thought possible.”
W.S.Anglin
REMEMBERREMEMBER
Curiosity and interest are the centre of inquiry!
Choose your investigation wisely!
Hope you are excited about
