Product Description

Our block sets are "Made in the USA". We manufacture in New England starting with hard maple lumber from the forests of the Northeast. We do not use "rubberwood" or the mixed species others refer to as "hardwood". Each set is built according to the "Unit Block" standard developed by educator Caroline Pratt in the early 1900's. The dimensions of each block shape is a multiple or a fraction of the size of the piece defined as the "unit". The "unit" is a rectangular piece of maple measuring 5 1/2" in Length by 2 3/4" in width by 1 3/8" in height or thickness. The name of each basic rectangular block shape in a set is based on its size as compared to the length of the "unit", e.g., the Unit Block is 5 1/2" long while the Half Unit Block is 2 3/4" long, the Double Unit Block is 11" long and the Quad Unit Block is 22" long. The dimensions of all other block shapes, including columns, pillars, triangles, curves, etc., are proportional to the length, width and height dimensions of the "unit". This is the source of the term, "Standard Unit Blocks". The fixed relationship between the "unit" and the other block shapes creates an environment in which children develop motor skills and "absorb" math concepts such as length, volume and fractions while totally engaged in the creative freedom of block play. Children "discover" the relationship between the different standard unit block shapes through play. They learn that two Unit Triangles make a Unit Block, etc..

Customer Reviews

BEST BLOCKS!
A very good friend of mine bought these blocks for my boys. She purchased them because we would really prefer made in the USA and they were solid wood - natural. They come in a cute little wheeled box which is great for teaching your children to load and unload, and organized. My kids problem solve to put them all back neatly. This is a great gift, they are expensive but worth it!
