What is the Original Polydron Platonic Solids Set?

The Original Polydron Platonic Solids Set (code 10-3000) is a 50-piece shape construction kit from Polydron for children aged 4 and over. It contains 32 equilateral triangles, 12 pentagons and 6 squares, supplied in 4 colours. The pieces snap together at the edges to form a strong hinge, so a flat net can be folded up into a solid shape.

What can you build with the Polydron Platonic Solids Set?

The set focuses on the five Platonic solids: the tetrahedron, cube, octahedron, dodecahedron and icosahedron. Between them these solids have 32 triangular faces, 6 square faces and 12 pentagonal faces, which matches the 50 pieces in the box. Each square measures 7.3 x 7.3 cm. The pieces also connect with Crystal Polydron, Polydron Frameworks, Polydron Bridges and Polydron Engineer, so the set can be added to over time.

For schools

• Supports the maths curriculum on 3D shape, nets, faces, edges and vertices across KS1 and KS2, with extension work at KS3.
• Lets pupils compare regular polyhedra by handling them, before moving to pictorial and abstract work, in line with Quality First Teaching.
• A compact 50-piece set that suits a small group, a maths table or an intervention session.
• Dishwasher safe at 70°C, which helps keep shared classroom pieces clean.

For parents and home use

• Gives children a hands-on way to explore 3D shapes at home.
• Joining and folding pieces offers regular fine motor practice.
• Free Exploring Polydron booklets can be downloaded from Polydron for activity ideas.
• Suitable from age 4, with enough challenge to interest older children.

Supporting learners with SEND and learning differences

Hands-on construction helps many learners with SEND and learning differences make sense of maths ideas that can feel abstract on paper. Children can hold a cube or an icosahedron, turn it and count its faces instead of picturing it. The bright pieces give clear visual cues, and snapping edges together builds fine motor control. Unfolding a solid back into a flat net makes the link between 2D and 3D shape concrete and easy to repeat.

The Original Polydron Platonic Solids 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 Platonic Solids Set?
  It is a 50-piece Polydron geometry kit made for building the five Platonic solids. The box holds 32 equilateral triangles, 12 pentagons and 6 squares in 4 colours. The pieces snap together with a hinged joint, so children can build a flat net and fold it into a tetrahedron, cube, octahedron, dodecahedron or icosahedron.
• What age is the Polydron Platonic Solids Set suitable for?
  Polydron states the Platonic Solids Set is suitable for children aged 4 years and over. Younger children can join shapes and make simple patterns, while older pupils can build all five Platonic solids and compare their faces, edges and vertices. The same set can therefore support learning across primary school and into secondary maths.
• How can teachers use the Platonic Solids Set in maths lessons?
  Teachers use it to explore 3D shape properties, nets and regular polyhedra. Pupils can build each Platonic solid, count its faces, edges and vertices, then unfold it to study the net. The compact 50-piece set suits a small group or intervention session, and the pieces are dishwasher safe at 70°C for easy cleaning.
• Is the Platonic Solids Set good for learning at home?
  Yes, it gives children a hands-on way to explore 3D shapes at home. Parents can download free Exploring Polydron booklets from Polydron for activity ideas, or let children experiment freely. Joining and folding the pieces gives regular fine motor practice, and building a solid from a flat net helps children feel confident with shape.
• 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. Holding a real cube or icosahedron 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 adapt tasks to suit each learner's pace.
• What comes in the Polydron Platonic Solids Set box?
  The box contains 50 Original Polydron pieces: 32 equilateral triangles, 12 pentagons and 6 squares measuring 7.3 x 7.3 cm, supplied in 4 colours. According to Polydron, the boxed set measures 25 x 24 x 3 cm and weighs 0.61 kg. Exploring Polydron activity booklets are available as free downloads from Polydron.
• Does the Platonic Solids Set work with other Polydron sets?
  Yes, the Original Polydron Platonic Solids Set is compatible with Crystal Polydron, Polydron Frameworks, Polydron Bridges and Polydron Engineer. Schools and families can add these sets later and combine pieces in bigger builds. This makes the 50-piece set a sensible starting point for exploring regular solids before moving on to larger collections.
