What is the Hashmag Polydron Class Set?

The Hashmag Polydron Class Set (code 55-8010) is a 72-piece magnetic construction kit from Polydron for children aged 3 and over. It contains 36 triangles and 36 squares in six translucent colours, plus a building guide. The pieces connect magnetically, so children can move quickly from flat designs to solid models.

What can a class build with 72 Hashmag pieces?

With 72 pieces, several children can build at once. They can join triangles and squares into 2D nets, then raise them into cubes, pyramids, prisms and larger structures. Colour coding on the pieces helps children understand polarity, so they can see which edges will attract. The translucent colours let light through, which adds interest to pattern and colour work. Hashmag is compatible with Magnetic Polydron, so the set can be combined with existing magnetic resources.

For schools

• Supports shape and space work in EYFS and KS1, from naming shapes to building simple 3D models.
• Links to KS2 maths on nets, faces, edges and vertices.
• 72 pieces give a small group enough material to build and compare models side by side.
• A concrete, hands-on resource for Quality First Teaching and SEND provision.
• Packed in a sturdy, reusable and recyclable carton for classroom storage.

For parents and home use

• A larger set for siblings or friends to build together at home.
• Magnetic pieces support open-ended play with quick, satisfying results.
• Joining and separating pieces gives regular fine motor practice.
• The building guide gives families ideas to start with.

Supporting learners with SEND and learning differences

Hands-on magnetic construction can help learners with SEND and learning differences make sense of shape and space. Children can hold a model, count its faces and pull it apart to see the net again. The translucent colours and colour coding give strong visual cues, and the magnets give instant feedback when two pieces connect. Repeating a build helps children practise at their own pace.

The Hashmag Polydron Class Set is available to order from The Dyslexia Shop, a UK specialist in resources for SEND and learning differences, for classrooms, nurseries and homes.

• What is the Hashmag Polydron Class Set?
  The Hashmag Polydron Class Set is a 72-piece magnetic construction kit made by Polydron. It contains 36 triangles and 36 squares in six translucent colours, plus a building guide. Children connect the magnetic edges to make 2D nets and 3D models, and the colour coding helps them understand magnetic polarity.
• What age is the Hashmag Polydron Class Set suitable for?
  The Hashmag Polydron Class Set is suitable for children aged 3 years and over. Younger children can make simple patterns and stacks, while older pupils can build nets, prisms and pyramids. As the set contains magnets, adults should supervise use and follow the safety warning supplied with the product.
• How many children can use the Hashmag Class Set at once?
  The 72 pieces in the Hashmag Class Set give a small group enough shapes to build at the same time. Teachers can split the 36 triangles and 36 squares between pairs or tables for shape tasks, then bring models together to compare faces, edges and vertices as a class discussion.
• Is the Hashmag Class Set a good choice for home?
  Yes, the Hashmag Class Set works well at home, especially for families with more than one child. The 72 magnetic pieces support open-ended building, and the included building guide offers ideas to start with. Connecting and separating the pieces gives regular fine motor practice and helps children feel confident with shapes.
• Is it suitable for children with SEND or learning differences?
  Yes, many children with SEND and learning differences benefit from hands-on resources like Hashmag Polydron. Building real shapes makes geometry something they can see, touch and count. The translucent colours and colour coding give clear visual cues, and the magnets connect easily. Adults can adjust tasks to suit each learner's pace and needs.
• Is Hashmag Polydron compatible with Magnetic Polydron?
  Yes, Polydron states that Hashmag is compatible with Magnetic Polydron. Schools that already own Magnetic Polydron can add the 72 Hashmag pieces to existing sets for bigger builds. This also means the Class Set can be extended later with further magnetic sets as children's skills and interest develop.
• How should the Hashmag pieces be cleaned?
  Polydron recommends sterilising Hashmag pieces with an alcohol-based sanitiser. This makes it simple to clean shared pieces between groups in a classroom or nursery. The pieces are BPA free, and the set is supplied in a sturdy, reusable and recyclable carton that works well for storage.
