What is the Magnetic Polydron Sphera Set?

The Magnetic Polydron Sphera Set (code 50-1110) is a 36-piece magnetic construction kit from Polydron for children aged 5 and over. It contains 8 sphere pieces, 4 cylinder pieces, 12 quadrant pieces, 4 cone pieces, 4 anti-quadrant pieces, 2 squares and 2 right-angle triangles, plus a poster to guide and start play. The set is made from 70% recycled plastic.

How does the Sphera Set help children learn about 3D shape?

Most first construction sets use flat-sided shapes. The Sphera Set adds curved pieces, so children can build more complex 3D shapes such as spheres, cylinders and cones. Polydron says the set will challenge children's learning as they combine geometry with magnetism. All pieces are magnetic, and the open frame pieces let children see inside their shapes. Squares measure 6 x 6 cm, and a model guide can be downloaded from the Polydron website.

For schools

• Extends 3D shape work in KS1 and KS2 beyond cubes and pyramids to spheres, cylinders and cones.
• Designed for small groups of children who have already mastered their first 3D shapes.
• Open frame pieces help pupils discuss curved and flat faces.
• A concrete resource that fits Quality First Teaching and SEND provision.

For parents and home use

• A next step for children who enjoy building with magnetic shapes.
• Encourages open-ended play with curved pieces that are new to most children.
• Joining the magnetic pieces builds fine motor skills and confidence.
• Suitable from age 5; not for children under 3 because of small parts and magnets.

Supporting learners with SEND and learning differences

Hands-on construction helps many learners with SEND and learning differences grasp shape ideas that are hard to picture from a drawing. Building a sphere or cone piece by piece shows how curved surfaces come together. The open frame pieces make the inside of each shape visible, giving clear visual support. Fitting pieces together also builds fine motor control, and models can be rebuilt as often as a learner needs.

The Magnetic Polydron Sphera Set is available to order from The Dyslexia Shop, a UK specialist in resources for SEND and learning differences, for small group work at school or learning at home.

• What is the Magnetic Polydron Sphera Set?
  It is a 36-piece magnetic construction kit from Polydron for building curved 3D shapes. The set includes sphere, cylinder, quadrant, cone and anti-quadrant pieces, plus squares and right-angle triangles. Children use it to build spheres, cylinders and cones, combining geometry with magnetism.
• What age is the Magnetic Polydron Sphera Set for?
  The Sphera Set is suitable for children aged 5 years and over. Polydron designed it for children who have already mastered their first 3D shapes. It is not suitable for children under 3 because of small parts, and the pieces contain magnets, so adult supervision is advised.
• What is included in the Sphera Set?
  The box holds 36 pieces and a poster. There are 8 sphere pieces, 4 cylinder pieces, 12 quadrant pieces, 4 cone pieces, 4 anti-quadrant pieces, 2 squares and 2 right-angle triangles. A model guide for the set can also be downloaded from the Polydron website.
• How can teachers use the Sphera Set in maths lessons?
  Teachers can use the Sphera Set to move 3D shape work beyond flat-sided solids in KS1 and KS2. Pupils build spheres, cylinders and cones, then compare curved and flat faces. Polydron recommends it for small groups, and the open frame pieces let pupils see inside each shape.
• Is the Sphera Set a good choice for home?
  Yes, it is a good next step for children who already enjoy magnetic construction at home. The curved pieces give new challenges compared with standard squares and triangles. Building spheres and cones supports fine motor skills and helps children feel confident with harder shapes.
• Is it suitable for children with SEND or learning differences?
  Yes, many children with SEND and learning differences benefit from building shapes with their hands. Making a sphere or cone piece by piece shows how curved surfaces fit together, which can be hard to picture on paper. The open frame pieces add visual support, and tasks can be broken into small steps.
• Is the Magnetic Polydron Sphera Set eco-friendly?
  Polydron states that the Sphera Set is made from 70% recycled plastic. The pieces are BPA free and the set comes in a recyclable carton. The pieces can be cleaned with an alcohol-based sanitiser, which helps a single set last through regular use at school or at home.
