Hardwood unit blocks have a way of drawing everyone to the rug, and the Whitney Brothers 170 Piece Quarter Unit Block Set gives young builders plenty to work with. With 170 blocks in 29 different shapes, there's room for a first tower or a sprawling city. We at The Sensory Supply, North America's specialist sensory store, chose this classic set for classrooms and family playrooms across Canada & the US.

Key Features of the Whitney Brothers Hardwood Unit Block Set

• Hardwood Construction - Every block has a solid, natural feel in the hand, making this wooden building block set a dependable choice for classrooms and homes.
• 170 Total Blocks - A generous piece count means several children can build side by side without running short, so group block play in preschools and daycares flows more smoothly.
• 29 Different Shapes - A wide mix of shapes invites children to experiment with balance and symmetry, so no two builds look the same.
• Smooth Natural Finish - Pleasant to touch and calm to look at, the natural wood lets imagination lead instead of bright colors.
• Rounded Edges for Safety - Softened edges make each block comfortable for small hands to grip and carry, giving educators and parents extra peace of mind during active play.

How Block Play Builds Fine Motor, Spatial, and Early STEM Skills

Stacking and bridging blocks asks hands and minds to work together. Researchers have linked early block building with stronger spatial reasoning and early math thinking, and children naturally pick up words like above and below as they build. OTs often use open-ended wooden blocks to practice grasp and hand-eye coordination. Because there's no single right answer, block play works for neurodiverse and neurotypical children alike, in solo or cooperative play.
