Our Big Kids Big Wooden Blocks Set of Standard Unit Blocks for homes, home schooling, home-based childcare, or family unit block play includes 24 of our larger wooden blocks in 5 classic standard unitblock shapes designed to support construction, tactile learning, and dramatic play for children ages 3 and up.

If you already bought a Melissa & Doug 60 Standard Unit Blocks set that you want to expand, then this set is for you. This set adds the larger block sizes that dominate quality unit block sets but are missing or under-represented in the Melissa & Doug 60 Standard Unit Blocks set.

In spite of the block count, this set contains 20% more building material than a Melissa & Doug 60 Standard Unit Blocks set. That’s because the Melissa & Doug 60 Standard Unit Blocks set is heavily weighted toward the smallest wooden block shapes and sizes in order to reduce shipping and manufacturing costs. Remember, their blocks are shipped all the way from Thailand and made of much cheaper, lighter, less durable Asian “hardwoods” like rubberwood.

Our Big Kids Big Wooden Blocks Set includes—

  • 12 – Basic Unit Blocks (5.5 x 2.75 x 1.375 inches)
  • 6 – Double Unit Blocks (11 x 2.75 x 1.375 inches)
  • 2 – Quadruple Unit Blocks (22 x 2.75 x 1.375 inches)
  • 2 – Double Pillar Unit Blocks (11 x 1.375 x 1.375 inches)
  • 2 – Double Unit Roof Planks (11 x 2.75 x 0.6875 inches)

Our wooden blocks are infant- and toddler-safe, suitable for ages 6 months and up, so you don’t have to worry about younger siblings putting these blocks in their mouths. They are completely free of borates, pesticides, and fungicides commonly added to rubberwood harvested in Southeast Asia. We use only 100% Hard Rock Maple. We manufactured each block in the United States from Custom Milled FSC®-Certified Hard Rock Maple. Each block is accurately cut to within half of 1/100 of an inch.

This 24-block set adds more FULL-SIZE unit blocks, DOUBLE unit blocks, AND QUADRUPLE unit blocks to your existing set, including 6 of the Double Unit Block shape and other larger shapes like Quadruple Unit Blocks and Double Unit Planks to support more larger building block contructions and dramatic play.

Compare Standard Unit Blocks & Wooden Blocks for Your Home

We use only durable, infant-safe Hard Rock Maple for our unit blocks for your home — never imported, chemically treated rubberwood or other soft hardwood. We cut each unit block to within one-half of one hundredth of an inch of standard unit block dimensions and round all edges for safety. We exceed CPSIA requirements.

We make it easy to upgrade. You can start with a smaller set for your home to meet immediate needs and upgrade whenever you wish. For an infant, toddler, or preschooler, start with the CP01 Infant Toddler Standard Unit Wooden Block Starter Set, the CP11 Introductory Family Standard Unit Wooden Block Set, or the CP31 Preschool Center Standard Unit Wooden Block Set and upgrade in easy, affordable steps to meet your budget.

Standard unit blocks in traditional hard rock maple are the classic educational toy — the perfect addition to your home. With sensible care, your set of Hard Rock Maple Unit Blocks will last generations and increase in value.

For home-based childcare, unit blocks are the one piece of play and learning equipment that meets the needs of all ages, from infant through elementary school.

Pay attention to the number of children you expect to play with these blocks simultaneously. Each booster set (CP02, CP03, CP04, CP05) adds blocks for an additional child and also supports age-appropriate play and additional dramatic and creative play possibilities home or home-based childcare. Our CP11 Introductory Family and CP31 Preschool Center wooden block sets include enough unit blocks for multiple children.

Buy with Confidence

Our Hard Rock Maple Unit Block Stock is never treated or sprayed with anti-fungals or insecticides because doesn't need to be — Hard Rock Maple hardwood is naturally insect- and mold-resistant. When your maple unit blocks get soiled, just wipe them off with a damp cloth and let them air-dry. Hard Rock Maple Unit Blocks typically last for decades when periodically cleaned and kept indoors. (We have some blocks that are almost a century old.)

We’ve taken an American education standard — the Unit Block — and provide a better block for your home — locally-made, sustainably produced, precisely and lovingly made, and ultimately safer for our children.

We use sustainably harvested, kiln-dried FSC Certified Hard Rock Maple, the only material we believe to be suitable for the full range of builders, from infants who put everything in their mouths to older adolescent siblings who build as high as they can reach.

We precision manufacture each block to within one-half of one hundreth of an inch in every dimension. We roundover every edge for safety.

We use only the time-tested proportions of the Standard Unit Block developed by educator Caroline Pratt one hundred years ago: 5.5 inches long, 2.75 inches wide, and 1.375 inches thick. Every block we produce is based on multiples of these basic measurements.

We offer an industry-leading 10 Year Warranty.

Please contact us if you would like to consult with an expert or just want a second opinion.

Because the costs of our raw materials, which make up about 1/3 of our retail price, are subject to change, we reserve the right to change our prices at any time and contact you to confirm permission to increase prices on orders not yet shipped. We will first make ever effort to reduce shipping costs to keep your total price the same.
