**‘On Track 4’** is a write-on student workbook that provides a comprehensive study programme for students wishing to sit any combination of the following NCEA Level 2 Mathematics Achievement Standards :

AS 2.1 - Apply co-ordinate geometry methods in solving problems

AS 2.2 - Apply graphical methods in solving problems

AS 2.3 - Apply sequences and series in solving problems

AS 2.4 - Apply trigonometric relationships in solving problems

AS 2.5 - Apply network methods in solving problems

AS 2.8 - Design a questionnaire

AS 2.9 - Use statistical methods to make an inference

AS 2.10 - Conduct an experiment to investigate a situation using statistical methods

AS 2.11 - Evaluate a statistically based report

AS 2.12 - Apply probability methods in solving problems

AS 2.13 - Investigate a situation involving elements of chance using a simulation

AS 2.14 - Apply systems of equations in solving problems

'On Track 4' is best bought at the start of the school year and used throughout the year as a homework resource. Alternatively, the book may be used as an independent study resource for use in the lead-up to internal and external assessments.

**‘On Track 4’** has 280 pages and covers NCEA Level 2 standards worth a total of 33 credits. Instruction boxes and worked examples appear on almost every page and help students with independent study. At the end of each chapter there is a valuable revision test which can be used by candidates to evaluate their strengths and weaknesses before assessments. A full set of answers is included, which can act as a guide to structuring quality answers. Sigma has now perforated all pages so that homework assignments can be handed in while work is ongoing and the answer pages may be retained by the teacher if desired.

Once completed, **‘On Track 4’** provides a useful set of study notes at assessment time. It should be kept as a reference book if students intend taking a Year 12 statistics course.
