• Supports 2D and 3D shape, nets, faces, edges and vertices at KS1 and KS2.
• Open Frameworks pieces let pupils see inside a 3D shape and count its edges.
• A compact 80-piece set for a small group, maths table or intervention session.
• Hands-on models support Quality First Teaching and SEND provision.
• Dishwasher safe at 70°C for easy cleaning.

For parents and home use

• A manageable starter set for open-ended building at home.
• Snapping pieces together gives regular fine motor practice.
• The downloadable model guide gives ideas when children want a challenge.
• Suitable from age 4, and works with other Original, Frameworks and Crystal Polydron sets as collections grow.

Supporting learners with SEND and learning differences

Hands-on construction helps many learners with SEND and learning differences understand shape ideas that can feel abstract on paper. Frameworks pieces show the edges of a shape clearly, while solid pieces show its faces, so children can compare the two by touch and sight. Joining pieces builds fine motor control, and models can be taken apart and rebuilt as often as needed.

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

• What is the Original Polydron Midi Box?
  The Original Polydron Midi Box is an 80-piece construction set that mixes open Frameworks pieces with solid Polydron pieces. It contains triangles and squares that snap together with a hinged joint, so children can build flat shapes and fold them into 3D models. A leaflet is included, and a model guide can be downloaded free.
• What age is the Polydron Midi Box suitable for?
  Polydron states the Midi Box is suitable for children aged 4 years and over. Younger children can join pieces and make simple shapes, while older children can follow the downloadable model guide or design their own 3D models. Its smaller size makes it a manageable first Polydron set for many families.
• What is the difference between Frameworks and solid Polydron pieces?
  Frameworks pieces have open centres, while solid Polydron pieces have filled faces. The Midi Box includes 55 Frameworks pieces and 25 solid pieces. Using both lets children see the edges of a shape through the frames and compare them with the solid faces, which helps when learning about faces, edges and vertices.
• Can teachers use the Midi Box in school?
  Yes, the Midi Box suits small group work, a maths table or an intervention session. Pupils can build 3D shapes and count faces, edges and vertices, using the open frames to see inside each model. The pieces are dishwasher safe at 70°C, and the box combines with other Original, Frameworks and Crystal Polydron sets.
• Is the Midi Box a good choice for home?
  Yes, the Midi Box is a compact starting point for building at home. Its 80 pieces come in a 22 x 22 x 15 cm box weighing 0.6 kg. Children can build freely or use the free model guide from Polydron, and snapping pieces together gives regular fine motor practice.
• 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. Seeing a shape's edges through open frames and its faces on solid pieces makes geometry easier to understand. Joining edges builds fine motor control, and models can be rebuilt as often as needed so adults can match the pace to each child.
• What comes in the Polydron Midi Box?
  The Midi Box contains 80 pieces and a leaflet. There are 24 Frameworks equilateral triangles, 13 Frameworks squares, 12 Frameworks right angle triangles, 6 Frameworks isosceles triangles, 20 Polydron equilateral triangles and 5 Polydron squares. It is compatible with all other Original, Frameworks and Crystal Polydron sets.
