Preschool Counts is a service-learning program in which Stanford undergraduates and master's students have an opportunity to help children from East Palo Alto develop their math skills so they are prepared to succeed in elementary school. In Preschool Counts, Stanford students, both undergraduates and master's degree students, are taught to provide an engaging, state-of-the-art early math program for preschool-age children at St. Elizabeth Ann Seton School.
