What can you build with Polydron Sphera?

Polydron Sphera lets children create their own spheres, cylinders and cones. With the 50 pieces in the Starter Set, children can build a sphere, hemisphere, cylinder, half cylinder, cone and half cone all at once. Polydron describes the set as suited to small groups of children and to understanding spherical models. The pieces come in 4 colours, and a free Sphera Assembly Guide is available to download from Polydron.

For schools

• Supports KS2 and KS3 maths on 3D shape, including curved surfaces, faces, edges and vertices.
• Six curved solids built at once let a small group compare spheres, cylinders and cones side by side.
• Concrete models support Quality First Teaching before pictorial and abstract work.
• Dishwasher safe at 70°C, so shared pieces are simple to keep clean.
• Useful in SEND provision and small intervention groups.

For parents and home use

• A compact starter set that introduces curved 3D shapes at home.
• Joining the pieces gives regular fine motor practice.
• The Exploring Sphera booklet gives parents ready-made activities.
• Suitable from age 8, with open-ended building once the core shapes are complete.

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. Curved shapes such as spheres and cones are hard to draw and picture, but a Sphera model can be held, turned and taken apart. The 4 colours give clear visual cues, and joining pieces builds fine motor control. Building a hemisphere and then a full sphere makes the link between the two shapes concrete.

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

• What age is Polydron Sphera suitable for?
  The Polydron Sphera Starter Set is suitable for children aged 8 years and over. At this age children are starting to study 3D shape properties in more depth, including curved surfaces. Older pupils and adults can also use the set to explore how spheres, cylinders and cones are built from smaller parts.
• How can teachers use the Sphera Starter Set?
  Teachers use the Sphera Starter Set to teach curved 3D shapes with a small group. Pupils build a sphere, cylinder and cone, then compare their faces, edges and vertices with flat-sided shapes. Polydron describes it as suited to small groups, and the pieces are dishwasher safe at 70°C for easy cleaning.
• Is the Sphera Starter Set good for home learning?
  Yes, the Sphera Starter Set is a compact way to explore curved shapes at home. Children can follow the Exploring Sphera booklet with a parent or build their own models. Joining the pieces gives regular fine motor practice, and taking shapes apart and rebuilding them helps children feel confident with 3D shape.
• Is it suitable for children with SEND or learning differences?
