Consolidating Applicable Mathematics (2nd Ed.)ISBN 0 9588575 9 8 This book provides a series of exercises, designed in most cases to supplement the work of a classroom teacher who would introduce material to students using a method appropriate to the subject matter, the students and the teacher. This introduction and concept development may involve investigative work with pen and paper, calculator or computer or whatever method deemed appropriate. 
Learning Applicable Mathematics (2nd Ed.)ISBN 1 875712 13 5 This book is designed to complement the "Consolidating Applicable Mathematics" text detailed above. 
40 Mathematical Newspaper SearchesISBN 0 9588575 0 4 This book contains forty mathematical activities that can best be described as "Newspaper Searches". The Newspaper Searches in this book are suitable for a variety of students and for inclusion in a variety of courses. Some of the newspaper searches could prove useful as part of the mathematics course for upper primary students whereas others have been developed specifically to increase the relevance of the mathematics in upper secondary school mathematics courses. Inside the book the specific objectives of each of the Newspaper Searches have been outlined. There is also some discussion on assessment, and sample marking guides of one type have been provided for all of the newspaper searches in the book.
