(Our blocks are designed for Ages 6 months and older.)

We'll be completely caught up on unit block orders when the postman picks up tomorrow, with no remaining orders to complete. Within two to three days, all packaged unit blocks will arrive at their new homes and Zero customers will be waiting on their orders.
The past six months have been an ordeal as we've struggled through fire and water (sprinkler system) damage, getting the shop back up and running, and waiting, waiting, waiting for the insurance company's builder to put back walls and restore electricity to the entire workshop.
Through it all, our customers have been amazingly understanding, patient, supportive, and encouraging. Thank You! We wouldn't be here without you!

October 15, 2011 — Share the joy of well-made hard maple unit blocks. These are the wooden blocks preferred by quality preschools, childcare centers, and elementary schools. These are NOT the cheap imitations made from foam, composite wood, rubberwood, or another unspecified soft hardwood, or non-specific "mixed" maple that splinter easily and won't pass the "Under Age 3" toy safety tests. These are NOT the bargain building blocks that are too light to be stable and not accurately cut which frustrates builders young and old. Carolina Pratt Standard Unit Blocks are Made in the USA and cut to an accuracy of one half of 1/100 of an inch. Perfect for the implicit learning of shapes and proportions built into dramatic play with quality wooden blocks.

Our Carolina Pratt Unit Blocks are precision manufactured to within one half of 1/100 of a inch by a real, live human being, using infant-safe Hard Rock Maple — the hardwood of choice for wooden blocks for toddlers and preschool Standard Unit Blocks — the original Standard Unit Block, made in the USA from domestic FSC® Mix Credit certified Hard Rock Maple.

What can you build with Carolina Pratt Unit Blocks?
How about healthy infants, toddlers, children, adults, schools, churches, and communities?
With our Hard Rock Maple Standard Unit Blocks, you can build just about anything.
We are building a better future — and so can you.
We make Wooden Unit Blocks because they inherently teach every subject matter.
Unit blocks set with blocks large and small help children develop gross and fine motor skills. Unit blocks are tools for building stories, developing language and conversational skills, confidence, and social competence through micro and macro dramatic play and through the simple act of giving words to describe what have been built.
Unit blocks teach proportions and math through hands-on, intuitive, self-correcting exploration.
Unit blocks encourage imagination, planning, experimentation, and problem solving. There is no one right way to play with unit blocks.
Although blocks have a fixed size and relationship to other blocks, teachers and parents will tell you that there are no limits to how young minds can play, create, imagine, and discover with a good set of unit blocks.
We use Hard Rock Maple because it is the safest material for little hands and mouths.
Hard Rock Maple, Hard Maple, Sugar Maple, Acer saccharum, call it what you will, it’s the same tree used to produce Maple Syrup, which is recommended (as is brown rice syrup) for allergy avoidance diets. Allergies to maple syrup, the concentrated sap, are rare. Allergies to maple wood are virtually unknown. Compared with birch and walnut, it’s the safest domestic hardwood for teethers. Maple wood is naturally anti-microbial, anti-fungal, and insect resistant without being toxic to children. Maple’s tightly interlocking grain and outstanding hardness make it the safe and durable wood of choice for preschool equipment as well.
We recommend against rubberwood, other Asian hardwoods, foam, cardboard, and plastic unit blocks. In addition to any health concerns, light weight blocks are easier to knock over, which is frustrating for young builders.
We source FSC® certified hardwood.
We choose the highest currently available certifications for the wood that goes into our unit blocks because FSC® inspection with a verifiable supply chain supports sustainable forestry for the health of the youngest generation and for generations to come.
The Forest Stewardship Council® has specific standards and chain of custody requirements that encourage not only sustainable forestry but also safe, legal, and socially responsible practices worldwide.
FSC® certifications can be used by schools and facilities to achieve goals for LEED Credit-Opportunity Contributions for Certified Wood and Low-Emitting Materials.
We clearly mark all our invoices as Made from FSC® Mix Credit Certified Hard Rock Maple for those buyers who require documentation.
