Maths tutor in Parramatta

The quick way wins

To go from square metres to hectares, divide by 10,000: move the decimal point four places. From hectares to square kilometres, divide by 100. Learners who remember that a hectare is a 100 m square never need a formula sheet for it.

A picture of 85 ha

A square with an area of 850,000 square metres has sides of about 922 m, since 922 times 922 is close to 850,000. That is a walk of just under a kilometre along each edge.

A size comparison only

Parramatta Park is about 16.2% of the suburb's area, but the park does not sit wholly inside the suburb boundary, so this is a comparison of sizes, not a share of land.

The common mistake

Students who know 1 m is 100 cm often assume 1 square metre is 100 square centimetres. It is 10,000, because both sides scale. The hectare table makes that visible.

Western Sydney Parklands, "Covering 5,280 hectares and stretching over 27 km", is about ten times the suburb of Parramatta.

Where it appears later

Area and volume conversions return in Years 9 and 10 measurement, in HSC Mathematics Standard, and in science practicals.

Getting the factor of 10,000 right once saves a lot of marks later.

The teacher's clock

Our teachers are in India, which has no daylight saving. In winter a Parramatta lesson at 5pm is 12:30pm for the teacher; in summer it is 11:30am. Families never need to work that out.

Holiday revision is available on request.

Private or a class

A private lesson suits a deadline or a specific gap. A class of fifteen to twenty at one level suits steady progress, with other students' questions often answering your own.

Both use a shared board so the teacher sees every step.
