Inspire little builders to construct and create with ECR4Kids Wooden Tunnels and Arches. From simple tunnels to elaborate city spaces, students employ problem-solving and critical thinking skills as they stack and build with increasing complexity. Open-ended play supports imagination, creativity, and helps develop independence as children design ramps, racetracks, and towers in countless arrangements. Use individually or pair up for teamwork, collaboration, and cooperative learning. The use of building toys introduces early math concepts including height, measurement, and balance to your child during playtime. Children can also explore the ability to create shapes with the curved blocks like flowers or circles on the ground. Learning shapes and sizes of the arches can help your kids distinguish between objects and grasp spatial reasoning. Enhance block play by combining multiple sets or pair with ECR4Kids Hollow Wooden Blocks, sold separately. Blocks are constructed from sustainably harvested birch plywood with a tough UV lacquer that seals the wood surface and resists scratching. A UV inhibitor makes shapes resistant to ultra-violet light and yellowing. Natural birch plywood is extremely durable and will hold up to everyday use in daycares and preschools, and early childhood environments.
