Play and Learn Preschool - the first step in your child's educational journey with Dassel-Cokato Schools. We are a public school readiness program for children ages 3 to 5. Understanding that young children learn best through play, your licensed early childhood teachers intentionally design the classroom environment to encourage exploration and learning through play following research-based curriculum and the State on Minnesota Early Learning Standards. Play and Learn Preschool embraces curiosity and hands-on problem solving while providing children with daily opportunities for social and emotional development.
