What is the Original Polydron Class Set?

The Original Polydron Class Set (code 10-3031) is a 184-piece shape construction kit from Polydron for children aged 4 and over. It contains 100 equilateral triangles, 40 squares, 24 pentagons and 20 hexagons, plus an Exploring Polydron activity booklet. The pieces snap together at the edges to form a strong hinge, so flat nets fold up into solid 3D shapes.

How does the Polydron Class Set help children learn?

The Class Set is designed to give a whole class enough pieces to explore basic geometry, shape and space. With 184 pieces in 4 colours, children can tessellate triangles, squares and hexagons, then fold nets into cubes, pyramids, prisms and other polyhedra. Each square measures 7.3 x 7.3 cm, a size small hands can grip and join. The pieces connect with Crystal Polydron, Polydron Frameworks, Polydron Bridges and Polydron Engineer.

For schools

• Supports the maths curriculum on 2D and 3D shape, tessellation, nets, faces, edges and vertices across KS1 and KS2, with extension work at KS3.
• Adds hexagons to the core shapes, so pupils can explore tessellation and a wider range of polyhedra.
• 184 pieces let several groups build and compare shapes at the same time.
• Gives a concrete model before pictorial and abstract work, in line with Quality First Teaching and SEND provision.
• Dishwasher safe at 70°C for easy cleaning of shared resources.

For parents and home use

• Offers plenty of pieces for siblings or friends to build together at home.
• Snapping the pieces together gives regular fine motor practice.
• The Exploring Polydron booklet gives parents ready-made ideas to start with.
• Open-ended building keeps children of 4 and over interested as their skills grow.

Supporting learners with SEND and learning differences

Hands-on construction helps many learners with SEND and learning differences understand maths ideas that can feel abstract on paper. Children can touch, turn and count the faces of a shape rather than imagining them. The bright pieces give clear visual cues, and joining edges builds fine motor control. Building, folding and unfolding a net makes the link between 2D and 3D shape concrete and repeatable.

The Original Polydron Class Set is available to order from The Dyslexia Shop, a UK specialist in resources for SEND and learning differences, for use in the classroom or at home.

• What is the Original Polydron Class Set?
  The Original Polydron Class Set is a 184-piece geometry construction kit designed for whole-class use. It contains 100 equilateral triangles, 40 squares, 24 pentagons and 20 hexagons that snap together with a hinged joint, plus an Exploring Polydron activity booklet. Children build 2D patterns and nets, then fold them into 3D shapes.
• What age is the Polydron Class Set suitable for?
  The Polydron Class Set is suitable for children aged 4 years and over. Younger children can join shapes and make simple patterns, while older pupils can build nets, tessellations and more complex polyhedra. Because the play is open-ended, the same set stays useful across primary school and can support extension work with older learners.
• Is the Polydron Class Set enough for a whole class?
  Polydron designed the Class Set to give a whole class enough pieces to explore basic geometry, shape and space. The 184 pieces can be shared between several groups so pupils build and compare shapes at the same time. Schools needing more pieces can combine it with other compatible Original Polydron sets.
• How is the Class Set different from the Polydron Basic Set?
  The Class Set adds 20 hexagons to the triangles, squares and pentagons found in the Basic Set. It contains 184 pieces in total: 100 equilateral triangles, 40 squares, 24 pentagons and 20 hexagons. The hexagons let pupils explore tessellation and build a wider range of shapes and polyhedra.
• Can the Polydron Class Set be used at home?
  Yes, the Class Set works well at home, especially for siblings or friends building together. Children can follow ideas from the Exploring Polydron booklet or invent their own models. Snapping pieces together gives regular fine motor practice, and folding a flat net into a solid shape helps children feel confident with maths ideas.
• Is it suitable for children with SEND or learning differences?
  Yes, many children with SEND and learning differences benefit from hands-on resources like Polydron. Handling real shapes turns abstract geometry into something they can see, touch and count. The bright pieces give clear visual cues, and joining edges builds fine motor control. Adults can adjust tasks to suit each learner's pace and needs.
• What is included in the Polydron Class Set and is it compatible with other sets?
  The box includes 184 pieces and an Exploring Polydron activity booklet. The pieces are 100 equilateral triangles, 40 squares measuring 7.3 x 7.3 cm, 24 pentagons and 20 hexagons in 4 colours. They are compatible with Crystal Polydron, Polydron Frameworks, Polydron Bridges and Polydron Engineer, and are dishwasher safe at 70°C.
