What is the Original Polydron STEM Set?

The Original Polydron STEM Set (code 10-7070) is a 486-piece construction kit from Polydron for children aged 9 and over. Polydron describes it as a foundation for higher level STEM learning. It explains STEM principles such as storing and releasing energy through models that children build and test.

How does the Polydron STEM Set support STEM learning?

The 486 pieces cover a wide variety of parts. Twenty-two work cards are arranged in three stages: Principles, Projects and Advanced Projects. This structure lets children learn a principle first, apply it in a project, then take on more demanding builds. A comprehensive 12-page teacher guide supports adults leading the sessions, and additional materials can be used alongside the set. The boxed set measures 47.5 x 30.5 x 14 cm, weighs 6 kg and comes in a sturdy reusable carton.

• A 12-page teacher guide helps staff plan and lead sessions with confidence.
• 486 pieces allow pupils to work in groups, and pieces are dishwasher safe at 70°C.
• Gives SEND provision and intervention groups a hands-on way into STEM ideas.

For parents and home use

• Suits home educators, STEM clubs and families with children aged 9 and over.
• Staged work cards build confidence, from simple principles to advanced projects.
• Building and testing models gives regular fine motor practice.

Supporting learners with SEND and learning differences

Hands-on construction helps many learners with SEND and learning differences understand ideas that can feel abstract on paper. Building a model that stores and releases energy lets children see a principle in action rather than imagining it. The staged work cards break learning into clear, manageable steps that can be repeated. Handling and joining the pieces also builds fine motor control.

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