Maths tutor in Brisbane

Entrance tests and national tests

Families looking at the Queensland Academies can read our Queensland Academies entry maths page. For national tests there is NAPLAN numeracy practice.

This page is about maths at every stage.

Typical requests

Catching up after a difficult unit, extension for a keen student, and adults preparing for a university bridging course.

The free first lesson shows which applies.

Where it winds most

Section 4 scores 2.62: its water travels more than two and a half times as far as a straight line would. Section 5, nearest the bay, is the straightest at 1.27.

Longer rulers cut corners

A 10 kilometre ruler skips every bend and measures only 47.81 kilometres, little more than half the channel. Every measured length depends on the step size.

When the simple ruler is enough

A 100 metre ruler gives 83.64 kilometres, within half a per cent of the full mapped line. Past that point, extra detail changes nothing worth knowing.

What students practise

Ratios, distance between points, adding many short lengths, and how a measurement depends on the instrument. Senior students connect it to arc length and limits.

Primary learners can trace the river with string on a printed map and compare it with a ruler.

Honest limits

The result depends on our rectangle and on how the map draws the river, so it describes this mapped stretch, not an official river length. We make no claim about the river's total length.
