Visit the Castro Valley Library for an afternoon of play and problem-solving at the Julia Robinson Mathematics Festival. At the festival, children and families will have the opportunity to explore a variety of fun, hands-on math puzzles and games. Activities are designed for children (and adults) of all ages and backgrounds, so everyone is welcome. Drop in and drop out whenever you’d like. Whether you stay for one puzzle or join us for the entire festival, we’re looking forward to seeing you for a day of joyful math!
