What is the Magnetic Polydron Sphera Class Set?

The Magnetic Polydron Sphera Class Set (code 50-1120) is a 72-piece magnetic construction kit from Polydron for children aged 5 and over. It contains 16 sphere pieces, 8 cylinder pieces, 24 quadrant pieces, 8 cone pieces, 8 anti-quadrants, 4 squares and 4 right-angle triangles, plus a poster to guide and start play. The set is made from 70% recycled plastic.

What can a class build with the Sphera Class Set?

The Sphera Class Set is designed for building more complex 3D shapes, including spheres, cones and cylinders. With 72 pieces, there is enough for a group to build several curved solids at once and compare them. All pieces are magnetic, and the open frame pieces let children see inside their creations. Squares measure 6 x 6 cm, and a model guide can be downloaded from the Polydron website.

For schools

• Extends KS1 and KS2 3D shape work to spheres, cylinders and cones.
• 72 pieces support whole-group or carousel activities.
• Suits pupils who have already mastered their first 3D shapes and need more challenge.
• A concrete resource that fits Quality First Teaching and SEND provision.
• Pieces can be cleaned with an alcohol-based sanitiser between groups.

For parents and home use

• A larger curved-shape set for families, home educators or clubs with several children.
• Encourages open-ended building with pieces that are new to most children.
• Joining 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 understand shapes that are difficult to picture from a flat drawing. Building a cylinder or cone piece by piece shows how curved and flat surfaces meet. The open frame pieces make the inside of each model visible, which gives clear visual support. Fitting the magnetic pieces together also builds fine motor control at a pace that suits each learner.

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

• What is the Magnetic Polydron Sphera Class Set?
  It is a 72-piece magnetic construction kit from Polydron for building curved 3D shapes in groups. The set includes sphere, cylinder, quadrant, cone and anti-quadrant pieces, plus squares and right-angle triangles. Children use it to build spheres, cones and cylinders and see inside them through open frame pieces.
• What age is the Sphera Class Set suitable for?
  The Sphera Class Set is suitable for children aged 5 years and over. It is designed 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.
• How can teachers use the Sphera Class Set?
  Teachers can use the Sphera Class Set to extend 3D shape lessons in KS1 and KS2. With 72 pieces, several groups can build spheres, cylinders and cones at once, then compare curved and flat faces. Pieces can be cleaned with an alcohol-based sanitiser between groups.
• What is included in the Sphera Class Set?
  The set contains 72 magnetic pieces and a poster. There are 16 sphere pieces, 8 cylinder pieces, 24 quadrant pieces, 8 cone pieces, 8 anti-quadrants, 4 squares and 4 right-angle triangles. A model guide for the set can also be downloaded from the Polydron website.
• Is the Sphera Class Set suitable for home learning?
  Yes, it works well for families with several children, home educators and clubs. The 72 pieces give enough for more than one child to build at the same time. Building curved shapes supports fine motor skills, open-ended play and growing confidence with harder 3D shapes.
• Is it suitable for children with SEND or learning differences?
  Yes, many children with SEND and learning differences benefit from building 3D shapes with their hands. Making a cone or cylinder piece by piece shows how surfaces fit together, which can be hard to picture on paper. The open frame pieces give visual support, and tasks can be broken into small steps.
• How is the Sphera Class Set different from the Sphera Set?
  The Sphera Class Set contains 72 pieces, double the 36 pieces in the standard Magnetic Polydron Sphera Set. It has the same seven piece types in larger quantities, which makes it better suited to whole-class or larger group work. Both sets are made from 70% recycled plastic.
