INTRODUCTION<br />

<strong>Problem</strong>-<strong>solving</strong> and mathematical thinking<br />

By learning problem-<strong>solving</strong> in mathematics,<br />

students should acquire ways of thinking,<br />

habits of persistence and curiosity, and<br />

confidence in unfamiliar situations that will<br />

serve them well outside the mathematics<br />

classroom. In everyday life and in the<br />

workplace, being a good problem solver can<br />

lead to great advantages.<br />

<strong>Problem</strong>-<strong>solving</strong> lies at the heart of mathematics.<br />

New mathematical concepts and processes have<br />

always grown out of problem situations and students’<br />

problem-<strong>solving</strong> capabilities develop from the very<br />

beginning of mathematics learning. A need to solve a<br />

problem can motivate students to acquire new ways<br />

of thinking as well as to come to terms with concepts<br />

and processes that might not have been adequately<br />

learned when first introduced. Even those who can<br />

calculate efficiently and accurately are ill prepared for<br />

a world where new and adaptable ways of thinking<br />

are essential if they are unable to identify which<br />

<strong>information</strong> or processes are needed.<br />

On the other hand, students who can analyse problem<br />

meanings, explore means to a solution and carry<br />

out a plan to solve mathematical problems have<br />

acquired deeper and more useful knowledge than<br />

simply being able to complete calculations, name<br />

shapes, use formulas to make measurements or<br />

determine measures of chance and data. It is critical<br />

that mathematics teaching focuses on enabling all<br />

students to become both able and willing to engage<br />

with and solve mathematical problems.<br />

Well-chosen problems encourage deeper exploration<br />

of mathematical ideas, build persistence and highlight<br />

the need to understand thinking strategies, properties<br />

and relationships. They also reveal the central role of<br />

sense making in mathematical thinking—not only to<br />

evaluate the need for assessing the reasonableness<br />

of an answer or solution, but also the need to consider<br />

the inter-relationships among the <strong>information</strong> provided<br />

with a problem situation. This may take the form of<br />

number sense, allowing numbers to be represented<br />

in various ways and operations to be interconnected;<br />

through spatial sense that allows the visualisation of<br />

a problem in both its parts and whole; to a sense of<br />

measurement across length, area, volume and chance<br />

and data.<br />

<strong>Problem</strong>-<strong>solving</strong><br />

A problem is a task or situation for which there is<br />

no immediate or obvious solution, so that problem<strong>solving</strong><br />

refers to the processes used when engaging<br />

with this task. When problem-<strong>solving</strong>, students engage<br />

with situations for which a solution strategy is not<br />

immediately obvious, drawing on their understanding<br />

of concepts and processes they have already met, and<br />

will often develop new understandings and ways of<br />

thinking as they move towards a solution. It follows<br />

that a task that is a problem for one student may not<br />

be a problem for another and that a situation that<br />

is a problem at one level will only be an exercise or<br />

routine application of a known means to a solution at<br />

a later time.<br />

A large number of tourists visited Uluru during 2007.<br />

There were twice as many visitors in 2007 than in<br />

2003 and 6530 more visitors in 2007 than in 2006. If<br />

there were 298 460 visitors in 2003, how many were<br />

there in 2006?<br />

For a student in <strong>Year</strong> 4 or <strong>Year</strong> 5, sorting out the<br />

<strong>information</strong> to see how the number of visitors each<br />

year are linked is a considerable task. There is also<br />
