CHALLENGE MATH FOR 5TH GRADERS, FIRST EDITION Published at Carleton College in Northfield, Minnesota. Copyright © 2008. Please contact Deanna Haunsperger, Carleton College Professor of Mathematics, at dhaunspe@carleton.edu to purchase a copy. 2
Special Thanks First and foremost, we’d like to thank our advisor, Deanna Haunsperger, for the guidance and assistance she provided throughout the project. We’d also like to thank April Ostermann for bringing us into her fifth grade class and for facilitating the teaching aspect of the project. We are also very grateful for the inspiration that Robert and Ellen Kaplan provided through their visit to Carleton College. Finally, the printing process would not have been possible without the generous help of the Carleton College Dean’s Office and the Carleton College Department of Mathematics. 3
