Giant building blocks turn abstract STEM ideas into something a whole class can build and rebuild with their own hands. The EverBlock Playground Play Mixed Block Set brings 668 life-size, interlocking blocks to classrooms, therapy rooms, and playrooms across North America, giving builders of every age a hands-on way to explore design, engineering, and spatial reasoning at full scale.

This isn't a scaled-down toy version of building - it's the real thing, sized for collaborative, whole-body play. Whether it's a reading nook raised by a small group or a full-scale fort built by a whole class, everyone gets a genuine stake in what goes up.

Key Features of the EverBlock Playground Block Set

• 668-Piece Mixed Assortment - A full mix of Full, Line, Half, Quarter, and Single Size blocks plus finishing caps in red, blue, yellow, green, and white gives builders enough variety to plan real structures, so group builds can grow as big as the room allows.
• Toolless, Pressure-Fit Assembly - Every block connects with a simple lug system that needs no tools to install or take apart, so a class can go from empty floor to finished structure within a single session.
• 3-Inch Staggered Building System - Unique lug spacing lets builders offset blocks in 3-inch increments to create patterns and load-bearing structures, turning basic stacking into a real engineering lesson.
• Hollow, Rib-Reinforced Construction - Internal support ribs keep each block strong and precisely fitted to the connector lugs below, so builds stay stable as they get taller.
• High-Impact, UV-Stable Polypropylene - A no-break polypropylene co-polymer with UV inhibitors means the blocks hold their colour and structure indoors or out, so one set moves between a classroom, a gym, and an outdoor STEM day.
• Easy-Clean Surface - A wipe-down with mild soap and a non-abrasive cloth keeps the set looking fresh through weekly use.
• Fully Recyclable & Reusable - Every block disassembles and rebuilds into something new, and the material is fully recyclable, supporting repeat-use programming over single-use activities.

Beyond the STEM connection, large-scale block building gives children a genuine workout for gross motor coordination, body awareness, and problem-solving as they lift, carry, and position full-size pieces. Planning and raising a structure as a group also builds turn-taking, communication, and shared problem-solving that smaller tabletop blocks can't replicate - benefits every builder experiences, neurotypical or not.
