Gretchen Paul

Gretchen Paul

Beginning School Director

“My favorite thing is to spend time in classrooms and outside and observe the students talking together, sharing discoveries, asking each other questions, and explaining their thinking to their peers. Not only do these interactions build social and conversational skills, but these conversations help to form ideas and connections in young minds. When children cooperate and engage with each other, learning can go further than it can alone!”
