This paper illustrates the use of computer-based projects in two one-semester first-year undergraduate mathematics classes. Developed over a period of years, the approach is one in which the classes are organised into work-groups, with computer-based projects being undertaken periodically to illustrate the class material. These projects are undertaken in computer labs using the Maple software package and have proved beneficial on two counts. First, in leading students to an understanding of mutual enterprise and encouraging them to participate in team activities, and, secondly, students have gained an enriched understanding of the classroom material. Nevertheless, student response remains variable with some students saying that they enjoy the additional exposure to mathematical ideas, while others dislike the additional work.
