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.

Thinking SkillsThinking SkillsThe type of skills normally associated with investigations are generally higher order skills or processes.

These processes fall under the broad heading of Working Mathematically in VELS. (Victorian Essential Learning Standards, VCAA)

“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.

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.

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
