Mathematics at Erina High

We aim to create engaging, creative and relatable lessons at Erina High. Students use a multitude of technological tools to test and solve problems. By encouraging students to think outside the box, we hope they will confidently tackle real life mathematical problems in their future.

Homework Club

On Wednesday Break 1, Break 2 and after-school a homework club is operating in D8  and staffed by current Mathematics teachers. If students are struggling with the work they should arrange a time (outside class time) to get assistance from their teacher or at the homework club, or speak to the Head Teacher - Mr Wade.


Mr. Wade (Head Teacher Mathematics) also provides great incentives for Year 7 and 8 students to become a part of STEM Club on Monday afternoons, after school. For more information check out our Clubs and Other Activities page

School A to Z

This is a very useful DEC website that provides practical information for parents.

Schoolatoz Link.

Under the 'Homework & Study" tab there is a Maths section that has a glossary of definitions, Maths help sheets, Maths tips, articles, videos and Maths assignment starters. 


All Mathematics courses are designed for the use of calculators. They are a necessary piece of equipment in today's society. 

The Year 7 and Year 9 NAPLAN tests have calculator and non-calculator papers.

The school DOES NOT supply calculators - they are a personal item that students need to purchase.

Any scientific calculator is suitable but the school recommends CASIO fx-82AU PLUS II. These are on special in stores at the start of the year.
