Year 9


Most homework will be set via the MathsBuddy system at www.mathsonline.com.au

Occasionally homework will be on paper, usually in the form of worksheets, or will be revision before a test.

A record of homework set will be kept at the Year 9 Homework Page.


In general the MathsBuddy system offers strong reinforcement, with immediate feedback, and so is ideal for normal homework. However, not every topic is covered to the same level so there will be times when no MathsBuddy suitable exercises are available.

Most exercises will be set to be completed by the following Sunday, although ideally they should be done before that. They remain active for some time afterwards, so boys can catch up on missed exercises. If they have forgotten how to do a topic, they should review the accompanying video.

The system has a log-in for parents who are interested in following their son's progress.

(It is strongly recommended that parents record their son's password somewhere easy to find, as they are often lost.)


For parents who want other or extra material, there are some relatively cheap books that give pages of homework exercises (along with quite useful notes and examples):

The Alpha Mathematics Workbook published by Pearson: www.pearsoned.co.nz

The Fast Track 1 from Eton Press is at a higher level, but covers the same basic material and is recommended for more able students: www.eton.co.nz

Revision and Support Material

The material on the Year 9 resources page of this site is generally to allow students to revise at the end of a topic or to catch up if they have missed some lessons. Most resources are paper worksheets, with worked answers, for the students to either do directly on the computer or print out.

The Year 9 on-line page gives links for students to get routine practice of fundamental skills from suitable websites.
