Children love to master this feat of engineering! The set of 114 smooth, hardwood blocks includes support pieces for use during the building process.
The moment of truth comes when you remove the building supports and—voila!—the arch stands on its own. A wonderful group activity, building the arch also develops fine motor skills, patience, and cooperation.
Set includes 14 different shapes, ranging from 1" square to 5¾" long. Includes instructions. Ages 5 and up; younger children may need adult supervision.
