The awarding of prizes for expository writing has long been one of the high points of MathFest. The Alder Award, for younger teachers, has added a prize for distinguished teaching to the annual MathFest awards ceremony.
The full prize booklet, which includes citations and responses by the winners, can be viewed with Adobe Acrobat Reader.
