Walker Maths Essentials is a series of workbooks for teachers to build courses appropriate to their students. In this way, students get resources pitched at the right level, to support their individual learning as they strengthen their skills in a particular strand. Each strand is supported by a set of four workbooks graded by curriculum level.

The well-designed, write-on workbooks contain teaching material, worked examples, carefully graded practice exercises, puzzles and challenges for those needing extension. Two comprehensive “test yourself” quizzes are provided at the end of each book.

We have taken all your favourite elements of the Senior Walker Maths series and incorporated them in to Walker Maths Essentials.

Digital Teacher Resources are available across all Walker Maths Essentials titles for teachers that adopt the corresponding workbooks. Each digital resource includes a Walker Maths Essentials projection file and Answers. Please contact your Learning Consultant for more details or email nz.sales@cengage.com
