Now Accepting Unit Block Orders for December 2021.
It's true that the best things in life are worth the wait. Your blocks are not sitting in a warehouse, waiting to be shipped. Your blocks are trapped inside our high-quality kiln-dried FSC®-certified hard rock maple precision-milled lumber, waiting to be set free. We build each set of standard unit wooden blocks as it is ordered. The sooner you order, the sooner we complete your blocks and ship them to you. Our cut off for Christmas orders is November 1st.

The World's Best Blocks for Kids
Unit Blocks for Your Family
Start with our CP01 standard unit blocks starter set for children of any age – ages one to ninty-one.
Add our CP02, CP03, CP04, CP05 unit block booster sets, at least one booster set per additional child, to build a classroom-quality set of standard unit blocks that would make Melissa and Doug jealous.
Unit Blocks for Your Classroom
Purchase our CP61 Quarter Classroom Set of Standard Unit Blocks in Hard Maple for 4 to 5 children of any age – or build your set incrementally with the standard unit block booster sets listed above and shown below.
Add our RX10 Booster set to add more of the most popular building block shapes to any set of Standard Unit Blocks. This 55-block booster set adds enough blocks for one more child. Each child in the block area needs 40 to 50 blocks to support parallel or cooperative play with peers.
Toddler-Safe Building Blocks for All Ages
Our toddler-safe standard unit blocks are Hand-Made-in-the-USA from Forest Stewardship Council® certified Hard Rock Maple. The edges and corners are all smoothly rounded, and our blocks are solid hard rock maple (sugar maple) with NO coatings of any kind. They're 100% pure sugar maple. Our unit blocks are fine for little hands and little mouths.
Our wooden block sets are designed for SUPERVISED PLAY for ages 6 months and above. To avoid head injuries, please don't allow kids (or adults) to build with blocks above their own heads or the heads of peers and younger siblings. Blocks are not about building until they fall on you or someone else. Blocks are tools for imagination.

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!

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.

Welcome to Carolina Pratt Unit Blocks.
We’re adding new photos of our Unit Blocks and additional information. If you don’t see what you’re looking for on our website, please call us or click the Live Help button for assistance.
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 FSC® Mix Credit certified Hard Rock Maple.
We are serious about making the best wooden blocks for your children at competitive prices including Free Shipping for our Hard Rock Maple Standard Unit Blocks via USPS Parcel Post and USPS Priority Mail.
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.
