What is the Hashmag Polydron Starter Set?

The Hashmag Polydron Starter Set (code 55-8000) is a 24-piece magnetic construction kit from Polydron for children aged 3 and over. It contains 12 triangles and 12 squares in six translucent colours, plus a building guide for inspiration. Polydron designed the set for individual or small group use.

What can children build with Hashmag Polydron?

Children join the magnetic pieces edge to edge to make flat 2D nets, then lift them into 3D models such as cubes and pyramids. The colour coding on each piece helps children understand polarity, so they can see why some edges attract and others push apart. The translucent colours let light through, which adds a visual layer to pattern work. Hashmag is compatible with Magnetic Polydron, so the 24 pieces can join a larger collection over time.

For schools

• Supports early shape work in EYFS and KS1, including naming triangles and squares and building simple 3D shapes.
• Links to KS2 maths on nets, faces and edges as pupils move from flat designs to solid models.
• Sized for one pupil or a small group, which suits intervention sessions and focused tasks.
• Gives a concrete resource for Quality First Teaching and SEND provision.

For parents and home use

• A manageable 24-piece set for open-ended magnetic play at home.
• Joining and separating pieces gives regular fine motor practice.
• The included building guide gives families ready ideas to try together.
• Packed in a sturdy, reusable carton for easy tidying away.

Supporting learners with SEND and learning differences

Hands-on magnetic construction can help learners with SEND and learning differences explore maths ideas that feel abstract on paper. Children can hold, turn and count the faces of a shape they have made themselves. The translucent colours and colour coding give clear visual cues, and the magnets give instant feedback when pieces connect. Building and rebuilding the same model lets children practise at their own pace.

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

• What is the Hashmag Polydron Starter Set?
  The Hashmag Polydron Starter Set is a 24-piece magnetic construction kit made by Polydron. It contains 12 triangles and 12 squares in six translucent colours, plus a building guide. Children join the magnetic edges to make flat 2D nets and 3D models, and the colour coding helps them understand how magnetic polarity works.
• What age is the Hashmag Polydron Starter Set suitable for?
  The Hashmag Polydron Starter Set is suitable for children aged 3 years and over. Younger children can enjoy joining pieces and making simple patterns, while older children can build nets and 3D shapes. Because the set contains magnets, adults should supervise play and follow the safety warning printed on the packaging.
• How can teachers use Hashmag Polydron in the classroom?
  Teachers can use Hashmag Polydron for focused shape work with one pupil or a small group. Children can name triangles and squares, build nets and fold them into 3D models, then count faces and edges. The 24-piece size suits intervention sessions, and the polarity colour coding can open up simple science talk about magnets.
• Is the Hashmag Starter Set good for home learning?
  Yes, the Hashmag Starter Set suits home learning because it is small, easy to store and quick to set up. Children can follow ideas in the included building guide or invent their own models. Joining and separating the magnetic pieces gives regular fine motor practice, and building a 3D shape from flat pieces builds confidence.
• 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. Holding real shapes turns abstract ideas into something they can see and touch. The translucent colours and colour coding give clear visual cues, and the magnets connect easily. Adults can adapt tasks to match each child's pace and needs.
• Is Hashmag Polydron compatible with other Polydron sets?
  Yes, Polydron states that Hashmag is compatible with Magnetic Polydron. This means the 12 triangles and 12 squares in the Starter Set can be combined with Magnetic Polydron pieces for larger builds. Families and schools can start small with this 24-piece set and add further sets later as children's interest grows.
• How do you clean Hashmag Polydron pieces?
  Polydron recommends sterilising Hashmag pieces with an alcohol-based sanitiser. This is a simple way to keep shared pieces clean in a classroom, nursery or therapy room. The pieces are BPA free, and the set comes in a sturdy, reusable carton that makes it easy to tidy everything away after use.
