City kids get the rare opportunity to learn in an outdoor classroom through this early-childhood program. Tots as young as 1 ½ will develop their motor and sensory skills, as well as self-esteem and focus via hands-on, group activities in many of Brooklyn green spaces, including Prospect Park, Marine Park, Owls Head Park and Shore Road Park. The natural environment plays a role in each lesson, whether inspiring discussion about the seasons or providing natural materials to use in crafts and “outdoor kitchen” cooking activities. Parents will need to pack a healthy snack and water, and make sure the kids are suited up in weather-appropriate gear for class. Ages 18 months–8 years.
