In these pages you will read about successes and also of indications where more effort and imagination is needed. You will read that the work continues and is unlikely to be any easier as we find new challenges in our paths. You will also read of the rewards for both teachers and learn- ers when connections are made and real learning occurs. The editors wish to thank the editorial committee for their support and hard work in bringing this proceedings to such a high standard in a short time. Members of the edito- rial committee are: Janette Bobis, Michael Cavanagh, Beth Southwell, Steve Thornton, and Paul White. We were greatly assisted in our task by Merrilyn Goos, who shared her experiences from the 2003 conference; and by Ann Belperio in the AAMT office. The panel of people to whom papers were sent for peer review was extensive and we wish to thank them all: Steve Arnold Sandra Frid Carolyn McGinty Howard Reeves Cathy Attard Sue Garner Mal McLean Noemi Reynolds Mary Barnes Vince Geiger Diane McPhail Dianne Siemon Dawn Bartlett Ann Gervasoni Ken Milton Len Sparrow Bernice Beechey Peter Gould Mike Mitchelmore Max Stephens George Booker Jim Green Will Morony Gloria Stillman Elizabeth Burns Peter Grootenboer Sharyn Moses Chris Stocks Rosemary Callingham Holly Gyton Greg Murty Paul Swan Mohan Chinnapan Anthony Harradine Denise Neal Jenny Tayler Garry Clark Judy Hartnett Zeffie Nicholas Sue Thomson Barbara Clarke Chris Horley Steven Nisbet David Tynan Rae Deeley David Keanan-Brown Peter Osland Elizabeth Warren Judith Falle Barry Kissane Kay Owens Jane Watson Rhonda Faragher David Leigh-Lancaster Cath Pearn Jenni Way Helen Forgasz Kym Linke Ray Peck Leigh Wood Pat Forster Tom Lowrie Thelma Perso Robert Yen Andrew Fraser Karen McDaide Cyril Quinlan Robyn Zevenbergen Editors: Mary Coupland, Judy Anderson, Toby Spencer. [ PREFACE ] ii MAKING MATHEMATICS VITAL: PROCEEDINGS OF THE TWENTIETH BIENNIAL CONFERENCE OF THE AUSTRALIAN ASSOCIATION OF MATHEMATICS TEACHERS Review process Submissions to the conference were called for in two formats, seminar papers and work- shops, with the possibility of either being subjected to peer review. These papers were reviewed blind by at least two reviewers. Papers were assessed as: 1. suitable for presentation at the conference and for publication in the proceedings, identified as ‘accepted by peer review’, 2. suitable for presentation at the conference and for publication in the proceedings, and 3. not suitable for the conference. Papers that were designated as (1) have been identified with an asterisk (*).

People are confronted with challenging situations each day and need to deal with them. Fortunately the processes in solving mathematics chal- lenges (abstract or otherwise) involve certain types of reasoning which generalise to solving challenges encountered in every day life. Mathematics has a vital role in the classroom not only
