“Maths is an essential skill and all skills have to be practised to become learned. I try to make my maths books interesting and use everyday situations to illustrate the use of maths. I believe write-on books reduce the tedium of copying out problems and make the practice required to become better at maths easier and more enjoyable for students.”

“I believe learning should be constructive and enjoyable. I have supported the exercises in my books with comical illustrations for students to enjoy and which illuminate the learning task. I hope students chuckle a little as they learn with my books and I hope I save busy teachers some preparation time which can be put to better use.”

David Wort

David Wort was born in the South Island and grew up in a variety of locations in New Zealand's rural heartland. He completed his first degree, majoring in English, French and History, at the University of Waikato. His Master's degree was taken at the University of Auckland and he trained as a teacher at Auckland Teachers' College. After some years teaching in Auckland and the arrival of the first of his four children, he moved to the Bay of Plenty where he has taught for over thirty years, many of them as a Head of Department. The introduction of NCEA presented new leadership responsibilities in resource creation and assessment which, along with the experience of teaching in the new system at all levels, have developed the practical insights so evident in the Achieving in English series. 

"I hope my books encourage students to discover the great truth about learning that Francis of Assisi put like this : Start by doing what's necessary, then do what's possible and suddenly you are doing the impossible."
