At 56 large 10cm foam blocks across 8 Signature shapes, recommended for 3-5 children, it is sized for the group construction contexts that the smaller BUILDER sets approach but cannot fully serve: a kindergarten construction zone where four or five children arrive simultaneously, an OT group session where the therapeutic goal is sustained collaborative building across a full group, a classroom where the teacher wants every child in a small group to have enough blocks to build independently before combining.

The arithmetic of group building at this block count is straightforward. Fifty-six blocks shared among five children gives each child approximately 11 blocks - enough to build a complete, recognisable structure at 10cm cube scale. Shared among three children it gives each roughly 18 blocks, enabling the most architecturally ambitious individual sub-builds in the BUILDER range. When those sub-structures are combined into a single group build, the result is a floor-spanning construction of 40 to 56 blocks that reaches heights of 40 to 60cm and spans a metre or more across the room. The four-kids lifestyle photograph in this set's imagery exists precisely because that group scale is what distinguishes the Builder 56 from everything below it in the range.

Each block is made from closed-cell EVA foam with a waterproof rotating neodymium magnet capsule. Every face of every block attracts every other face in any orientation - no wrong connections, no failed placements. The blocks are EN71-certified, BPA-free, non-toxic, and disinfectable. The set includes a storage bag and is fully compatible with all other TUKI BIG BUILDER and SMART sets. 

Key Features of the TUKI BIG Magnetic Blocks Set - Builder 56

• 56 Large 10cm Magnetic Foam Blocks - Recommended for 3-5 Children - The second largest BUILDER set in the TUKI BIG range provides the block volume for genuine 3-5 child group construction; each child in a group of five has approximately 11 blocks, enough to build independently and combine into a shared floor-spanning structure
• 8 Signature TUKI Block Shapes - The same full 8-shape vocabulary as the Builder 43 - cubes, beams in multiple variants, L-shapes, and triangles - providing the complete geometric range for complex, architecturally varied group builds at floor scale
• 10cm x 10cm x 10cm Large-Format BIG Blocks - Each block is a full 10cm cube, twice the linear dimension of the Regular range and eight times the volume per block; floor-scale, both-hands, whole-body building blocks that develop gross motor planning, bilateral coordination, and proprioceptive body awareness at a physical scale that tabletop construction cannot match
• Rotating Neodymium Magnet Capsules - Full-Angle Connectivity - Every face of every block attracts every other face in any orientation; no wrong connections, no repelling faces - reliable magnetic connectivity at the frequency and variety of 3-5 child group building where dozens of connections are made across a session
• Four Colours - Turquoise, Grey, Yellow and Pink - Fifty-six blocks across four colours provides enough of each colour for deliberate single-colour sub-builds by individual children, colour-matched section assembly, and the colour-based group negotiation that large-format multi-child construction naturally generates
• Closed-Cell EVA Foam - Waterproof, Disinfectable and Floating - Made from closed-cell EVA foam that does not absorb water; blocks wipe clean or disinfect in seconds between sessions, meeting the hygiene standards required in kindergartens, therapy rooms, and institutional settings where multiple groups use shared equipment throughout the day
• EN71-Certified, BPA-Free and Non-Toxic - Certified to EN71-1, EN71-2, and EN71-3 European toy safety standards; BPA-free and non-toxic; independently safety-tested; appropriate for use in all regulated early years, therapy, and institutional settings serving groups of children
• Compatible with All TUKI BIG BUILDER and SMART Sets - Every block is fully compatible with all other TUKI BIG products; settings that already own Builder 12, Builder 26, or Builder 43 sets can combine them with the Builder 56 to build a single collection that scales beyond 56 elements
• Storage Bag Included - The set includes a storage bag designed for institutional group use - pack-away, transport between rooms, and hygiene between group sessions are all supported
• Poland's Toy of the Year 2023 - Made in Poland - Awarded Poland's Toy of the Year 2023; manufactured in Poland to EN71 European standards

Why 56 Blocks Changes the Group Construction Experience

The progression from Builder 43 to Builder 56 is not primarily about architectural ambition - it is about group size. The Builder 43 serves 2-3 children well and begins to serve 4 children adequately. The Builder 56 is the first BUILDER set where a group of 5 children all have enough blocks to participate meaningfully in the same floor build simultaneously, without one or two children waiting for blocks to become available from a collaborator's structure.

That matters in institutional settings for a specific reason. Group therapy sessions, classroom construction activities, and kindergarten free-choice time do not always allow an educator to manage the block allocation within a group carefully. When there are enough blocks for every participant to build independently before combining, the session requires less adult management of the resource - children self-organise, build at their own pace, and bring their sub-structures to the group build when ready, rather than competing for a limited pool of shared pieces. The Builder 56 reaches that self-organising threshold for groups of five.

Skills and Developmental Outcomes

• Collaborative Construction and Social Communication at Group Scale - Building with 3-5 children using a shared pool of 56 blocks generates sustained turn-taking, negotiation, shared planning, and joint decision-making; with enough blocks for each participant to build independently and combine, the collaborative dynamic is self-organising rather than adult-managed
• Gross Motor Planning, Bilateral Coordination and Core Strength - Lifting, carrying, and placing 10cm large-format foam blocks across an extended group build develops bilateral coordination, motor planning, core stability, and whole-body spatial awareness at a physical scale distinct from tabletop construction
• Spatial Reasoning and 3D Engineering at Architectural Scale - Combining 8 distinct shapes across 56 blocks to build stable, architecturally varied floor structures develops spatial reasoning, structural problem-solving, and early engineering thinking at the most complex scale the BUILDER range provides
• Executive Function, Planning and Cognitive Flexibility - Coordinating a 3-5 child group build requires planning, role allocation, structural decision-making, and the cognitive flexibility to adapt when a section does not work as intended - a multi-step executive function challenge that sustained large-group floor construction uniquely generates
• Proprioceptive and Tactile Sensory Processing - Repeated lifting, carrying, and placing of 56 large EVA foam blocks across an extended group session provides sustained proprioceptive input and rich tactile engagement; the physical demands of this scale of floor building are a whole-body sensory experience
• Creative Expression and Narrative Construction at Full Group Scale - Fifty-six blocks in 8 shapes across 3-5 children sustains the richest open-ended imaginative group construction this BUILDER range provides; builds are large enough to span a room and sustain narrative projection across a full group session
