Delta Mathematics Workbook

Practice and consolidate skills

The author team of David Barton and Anna Cox has been joined by Philip Lloyd to provide an easy-to-use, write-on workbook. It contains approx 80 self-contained assignments linked to the Delta Mathematics textbook, making it easy for the teacher to give practice to students without having to devise new work. It contains a huge array of exercises that are linked to the corresponding Delta Mathematics. This makes it easy for teachers to choose, and students to remember, homework, extra practice and revision exercises that match what has been done in class.

This workbook can be used alongside any mathematics textbook, and contains the worked examples, content summaries, and real-world, in-context problems, investigations and puzzles that David Barton is famous for – encouraging all students to gain and demonstrate a thorough understanding of mathematical concepts at NCEA Level 3.

The 3rd edition of Delta Mathematics is closely aligned with developments in New Zealand mathematics education. The content has been carefully revised in line with best teaching practice, and expanded to respond to changes in the curriculum and assessment. Delta Mathematics covers all eight of the NCEA Level 3 Mathematics Achievement Standards.

Delta Mathematics includes a balanced coverage of critical-path analysis, a new area in secondary mathematics, and incorporates:

• critical-path method (earliest and latest start and finish times)
• the backflow algorithm
• scheduling, with both unlimited and limited processors
• allocation of tasks, with priority lists based on critical times and decreasing times.

All the topics in Delta Mathematics are accompanied by a large number of well-balanced questions, graded in difficulty, to reinforce students' understanding and build solid foundations for future learning. Many investigations, applications, spreadsheet activities and puzzles help to make the underlying mathematics more interesting and relevant. Full answers are provided.
