Year 9 Maths by Norman J Wildberger

This series is aimed at Year 9 Maths students, primarily in Australia, but also beyond. The new Australian national curriculum in mathematics introduces new challenges for both students and teachers. I am aiming for a leisurely but concise overview of this curriculum, starting with a review of arithmetic with integers, fractions and decimal numbers. This series will have practice problems for students to do as they go along. It may be viewed in sequence, or dipped into for individual topics. Comments and suggestions by high school teachers are particularly valued: send me your feedback please!
