What is the Polydron KinderMag Class Set?

The Polydron KinderMag Class Set is a 96-piece magnetic construction set for children aged 12 months and above, comprising 48 squares and 48 triangles made from 70% recycled plastic. The pieces connect with a satisfying snap using built-in magnets, allowing young children to explore 2D patterns and 3D structures without the frustration of fiddly connectors. Designed by Polydron, a UK-based manufacturer of educational construction resources, KinderMag gives the youngest learners a first experience of magnetic building.

How it helps in early years settings

Magnetic construction play supports a range of early developmental goals. Handling and connecting the chunky 7cm pieces builds fine motor control and hand-eye coordination in children who are still developing grip and pinch strength. Exploring which shapes fit together and how flat pieces fold into 3D forms develops early spatial reasoning and an intuitive feel for geometry. The four speckled pastel colours also provide a gentle introduction to colour recognition and simple sorting activities.

For children with additional needs, including those with dyspraxia, developmental coordination difficulties, or delayed fine motor skills, the large piece size and strong magnetic connection reduce the physical demand of building, allowing focus to stay on exploration and creativity rather than manipulation.

Why it works in nurseries and primary classrooms

• Large, chunky pieces designed for small hands: at 7cm x 7cm, the squares are easy to grasp and position, making the set accessible for children from 12 months through to early primary school years.
• Durable and easy to clean: the tough recycled plastic construction is built for repeated classroom use, and pieces can be sterilised with an alcohol-based sanitiser, meeting nursery hygiene requirements.
• Environmentally responsible choice: made from 70% recycled plastic and supplied in a recyclable carton, the KinderMag Class Set supports schools and settings with sustainability commitments.
• Whole-class resource: with 96 pieces included, the class set provides enough material for group activities and shared exploration without needing multiple purchases.
• Comes with a model guide: the included guide gives practitioners and parents starting-point models to follow, supporting structured play alongside free exploration.

Suitable for home use too

The KinderMag Class Set works equally well at home. Parents supporting children with developmental delays, fine motor difficulties, or sensory sensitivities will find the gentle pastel colours and satisfying magnetic connection particularly helpful for encouraging independent play and early construction skills.

Why magnetic construction supports development

Research into early childhood development consistently highlights the importance of hands-on, manipulative play for building the foundational skills children need in literacy and numeracy. Magnetic construction sets encourage sustained attention, problem-solving, and spatial thinking, all of which underpin later learning. For children with dyspraxia or developmental coordination disorder, activities that build fine motor strength and hand-eye coordination are directly recommended as part of a supportive approach.

• What is the Polydron KinderMag Class Set?
  The Polydron KinderMag Class Set is a 96-piece magnetic construction set for children aged 12 months and above. It includes 48 squares and 48 triangles made from 70% recycled plastic that snap together with built-in magnets to build 2D patterns and 3D models. A model guide is included to support structured play.
• What age is the KinderMag Class Set suitable for?
  The KinderMag Class Set is designed for children aged 12 months and above. The chunky 7cm pieces are large enough to be safe and manageable for toddlers, and the set remains engaging through nursery and early primary school years. It is safety tested for children from 12 months.
• How does the KinderMag Class Set support children with dyspraxia or fine motor difficulties?
  The KinderMag Class Set is well suited to children with dyspraxia or developmental coordination difficulties because the large piece size reduces the demand on fine motor control, and the magnetic connection means pieces do not need to be slotted or clipped together. Children can focus on building and exploring without frustration from fiddly fastenings.
• How many pieces are in the Polydron KinderMag Class Set?
  The class set contains 96 pieces in total: 48 triangles and 48 squares. A model guide is also included. The pieces are available in four speckled pastel colours made from 70% recycled plastic.
• Is the KinderMag Class Set suitable for use in a nursery or classroom?
  Yes, the KinderMag Class Set is designed for nursery and early years classroom use. The pieces are tough, BPA free, and can be sterilised with an alcohol-based sanitiser. With 96 pieces in a reusable carton, it provides enough material for group activities and is straightforward to store and distribute.
• What skills does magnetic construction play develop in young children?
  Magnetic construction play supports fine motor control, hand-eye coordination, spatial reasoning, early maths concepts such as shape and symmetry, and sustained attention. For children with learning differences, including dyspraxia and developmental coordination disorder, hands-on manipulative play of this kind is widely recommended by occupational therapists as part of a supportive approach to building foundational skills.
• Is the Polydron KinderMag Class Set made from recycled materials?
  Yes. The KinderMag Class Set is manufactured from 70% recycled plastic and supplied in a recyclable carton. It is also BPA free. Polydron is a UK-based manufacturer committed to more sustainable production of educational construction resources.
• Can the KinderMag pieces build three-dimensional models?
  Yes. The KinderMag squares and triangles connect magnetically on all edges, allowing children to fold flat pieces into three-dimensional shapes and structures. The included model guide shows a range of 2D and 3D builds, from simple flat patterns to more complex geometric models suitable for older children within the age range.
