Maple has a number theory package, which makes explorations of the concepts we have encountered possible on even very large numbers. Here you will find some worksheets that the instructor has found useful. They were written on a variety of copies of Maple, including versions 6, 7, and 9. The worksheets can be found here. Since a Maple 9 worksheet has a hard time running on a previous version, the commands used are also available in text files here.
