Simple, elegant, and open-ended. MAD Constructs architectural blocks challenge builders to “think outside the box.” While playing with these blocks, children and adults alike figure out how to combine straight sides and curves to make familiar shapes. That’s how MAD Constructs develops three-dimensional thinking. While playing together adults encourage children to think about these blocks in new ways. They may ask,”How do they feel?” Or “what do they remind you of?” They may ask more concrete questions, such as “how many blocks are in a circle?” Shared play and conversation enhance the child’s understanding of language, mathematics, the physical world, and aesthetics and enrich the parent and child relationship. Block play develops eye-hand coordination, fine motor and problem solving skills. Set includes six square and six arc blocks in a wooden tray. Invite spontaneous play. Place on a table and watch what happens.
