## Maths Enrichment

### Date

April – October 2023

## Time

12–16 weeks

## Cost

AUD$50 per student

Maths Enrichment is an extension program for talented students to widen their mathematical knowledge and skills.

Teachers receive comprehensive printed support material to extend both student learning and their own mathematical teaching practice. Enrichment material develops mathematical concepts not covered by the standard curriculum. Printed materials can be retained by students as an enduring reference through their school years.

Teacher sets include:

- a Teacher Guide with full problem solutions and detailed marking schemes
- one Student Problems booklet per student with unique problems each year
- one Student Notes book per student with a structured course of extension material.

Maths Enrichment is designed to be run over 12–16 weeks, with around 1 hour of class time and around 2–3 hours of individual study time per week.

Like all our competitions and programs, Maths Enrichment contains unique problems designed each year by leading educators and academics to challenge and extend your students’ problem-solving skills.

### Divisions

Stages are not limited to school years, however general recommendations are as follows:

**Ramanujan**– Australian Years 4 and 5**Newton**– Australian Years 5 and 6**Dirichlet**– Australian Years 6 and 7**Euler**– Australian Years 7 and 8**Gauss**– Australian Years 8 and 9**Noether**– Capable or very capable Australian Years 9 and 10**Pólya**– Top 10% Australian Year 10

## Question and Answer Format

- Ramanujan, Newton, Dirichlet – 8 problems, written answers
- Euler, Gauss – 12 problems, written answers
- Noether, Pólya – 16 problems, written answers

## Delivery Option

- Printed problems provided, marking is done by teacher and marks submitted online
The experience of teachers using this program has been that students’ understanding of the problems is enhanced when teachers mark the student submissions and use the materials provided to give feedback.
