Tinkergarten

Some of the best learning moments take place outdoors in nature's classroom. Tinkergarten's curriculum is built upon research that suggests that time spent outdoors can significantly improve relationship skills and reduce common unpleasant emotions. When 'Tinkergarteners' are outdoors with relaxed inhibitions they're able to problem solve and get creative with instinctive activities like playing with mud, finding bugs and making stone soup. It may sound simple, but class leaders have a way of bringing all of those outdoorsy Pinterest activities to life in such a simplistic and entertaining manner. This is another multi-age program with younguns 18 months - 5 years in class together––but the teachers are expertly trained in slicing up one lesson and dishing out appropriate slices so that every age gets the most out of each lesson. The fee is $180/session and a 50% discount is offered for siblings.
