BLOCK Fest® is a research-based exhibit that helps raise awareness of early math and science learning by offering hands-on block play experiences to families with young children. Parents, preschool teachers, and the community will become more knowledgeable about the importance of early math and science learning as it impacts both school readiness and later math success. Block Fest is owned by the Twiga Foundation in Boise, Idaho.

Block Fest was developed to provide an interactive block building experience for young children ages 8 months to 8 years and their parents. Block Fest supports parents and children to form an emotional bond during the learning experience. The exhibit has been shown to increase parent knowledge of early development in the areas of math and science education while providing opportunities to increase social skills and literacy opportunities for young children. Block Fest also educates communities about the short and long-term importance of early math and science learning.
