The series of books create a course of study from Years 7 to Years 10 using the CSF and the Sample Course as their base. The authors have also added in extra areas of study where practising teachers have requested that these areas remain part of their teaching. Thus, Essential Mathematics for the CSF is a complete course of study which is CSF specific and reflects the needs of teachers of mathematics in Victoria and builds on long standing successful classroom teaching practices. The material has been extensively trialled in schools. Together with the exciting full colour and creative design makes this series a new step in the creation of maths resources for Victorian schools.
