A festival celebrating the science of playful learning
The Ultimate Block Party
The Ultimate Block Party was a large-scale public festival designed to highlight the power of playful learning in community spaces. First launched in 2010 in New York City’s Central Park, the event brought together scientists, educators, designers, and families to demonstrate how play can spark meaningful learning across multiple domains.
Through a series of interactive outdoor installations, the Ultimate Block Party engaged children and caregivers in activities that were fun, active, socially interactive, and intellectually stimulating. Each experience was intentionally designed to support the 6Cs—communication, collaboration, content knowledge, critical thinking, creative innovation, and confidence—by inviting participants to build, experiment, move, create, and problem-solve together. By transforming a public park into a vibrant festival of learning, the event showcased how everyday spaces can become powerful environments for joyful, research-informed engagement.
The Team
The Ultimate Block Party was conceived through a collaboration between Kathy Hirsh-Pasek (Temple University), Roberta Michnick Golinkoff (University of Delaware), Dorothy Singer (Yale University), Susan Magsamen (Johns Hopkins University), along with The Goddard School, LEGO Foundation, and KABOOM!.
