We describe several service-learning initiatives implemented by the mathematics and education departments. College students with majors and minors in math and math education have helped to design and implement math events for elementary and middle school students. Formal and informal reflections on these service-related experiences have demonstrated the potential impact on future teaching and learning goals for the pre-service teachers. College students taking a statistics course have analyzed data from some of these math events, using both descriptive and inferential methods. Teachers of participating elementary and middle schools have re-examined their textbook and curriculum choices in light of their students' performance at these math events. (Contains 1 footnote.)
