Of all the playthings in the history of the world, blocks may be the most important, because a child's imagination is required to bring them to life. Building with blocks, children create castles, roadways, playhouses, forts, garages, stables and more. Building with blocks, children also grasp basic number concepts and learn logic skills. When you give children blocks, you're giving them tools to build minds and develop unlimited imagination. The Standard Block set comes with 36 blocks in 11 different shapes: 6-half units 4-units 2-double units 4-half pillars 4-pillars 2-double pillars 4-columns 2-Roman arches 2-half ciricles 2-small triangles 4-double flats.
