The pressure to teach academic skills in pre-K and kindergarten has been increasing since the passage of the No Child Left Behind act 15 years ago. Today, many young children are required to sit in chairs, sometimes for long periods of time, as a teacher instructs them. This goes against their natural impulse to learn actively through play where they are fully engaged–body, mind, and spirit.Play is an engine driving children to build ideas, learn skills and develop capacities they need in life. Kids all over the world play and no one has to teach them how. In play children develop problem solving skills, social and emotional awareness, self-regulation, imagination and inner resilience. When kids play with blocks, for example, they build concepts in math and science that provide a solid foundation for later academic learning. No two children play alike; they develop at different rates and their different cultures and life experiences shape their play. But all children learn through play.
