What is the Original Polydron School Geometry Set?

The Original Polydron School Geometry Set (code 10-3020) is a 268-piece geometry kit from Polydron for children aged 4 and over. It contains 266 shapes and 2 Polydron protractors: 80 equilateral triangles, 40 right angle triangles, 60 isosceles triangles, 24 root 2 triangles, 30 squares, 20 hexagons and 12 pentagons. The pieces snap together at the edges to form a strong hinge.

How does the School Geometry Set support maths?

Seven shape types in 4 colours let pupils compare different triangles, build tessellations and fold nets into prisms, pyramids and other polyhedra. The 2 Polydron protractors add angle work to shape building. Each square measures 7.3 x 7.3 cm. Polydron states the pieces are BPA free and 100% recyclable, and they connect with Crystal Polydron, Polydron Frameworks, Polydron Bridges and Polydron Engineer.

For schools

• Supports 2D and 3D shape, types of triangle, angles, nets, faces, edges and vertices across KS1 and KS2, with extension work at KS3.
• 268 pieces give enough shapes for several groups to work at once.
• Protractors let pupils measure and compare angles on the shapes they build.
• Concrete models support Quality First Teaching and SEND provision before pictorial and abstract work.
• Dishwasher safe at 70°C, which helps keep shared resources clean.

For parents and home use

• Gives home learners a wide range of shapes to explore at their own pace.
• Joining pieces offers regular fine motor practice.
• Free Exploring Polydron booklets can be downloaded from Polydron for activity ideas.
• Open-ended play stays interesting from age 4 into secondary maths.

Supporting learners with SEND and learning differences

Hands-on construction helps many learners with SEND and learning differences make sense of geometry that can feel abstract on paper. Holding a right angle triangle beside an isosceles triangle shows the difference clearly, and a protractor on a real shape makes angle work more concrete. The bright pieces give clear visual cues, and joining edges builds fine motor control.

The Original Polydron School Geometry 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.

• What is the Original Polydron School Geometry Set?
  The Original Polydron School Geometry Set is a 268-piece maths construction kit. It contains 266 snap-together shapes, including equilateral, right angle, isosceles and root 2 triangles, squares, hexagons and pentagons, plus 2 Polydron protractors. Pupils use it to build 2D shapes, nets and 3D solids, and to explore angles.
• What age is the Polydron School Geometry Set suitable for?
  Polydron states the School Geometry Set is suitable for ages 4 years and over. It carries a choking hazard warning and is not suitable for children under 3. Younger children can make patterns, while older pupils can compare triangle types, build nets and measure angles with the included protractors, so it supports maths across many year groups.
• How can teachers use the School Geometry Set in lessons?
  Teachers use it to teach 2D and 3D shape, types of triangle, angles, nets and properties of solids. Pupils can build a shape, measure its angles with a Polydron protractor, then fold a net into a solid. The 268 pieces support several groups at once, and the pieces are dishwasher safe at 70°C.
• Can the School Geometry Set be used at home?
  Yes, it suits home educators and families who want a wide range of shapes. Children can build freely or use the free Exploring Polydron booklets that Polydron offers as downloads. Joining the pieces gives regular fine motor practice, and turning a flat net into a solid helps children feel confident with geometry.
• 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. Comparing real triangles side by side makes shape properties easier to see than on paper, and protractors on real shapes make angles concrete. The bright pieces give clear visual cues, and adults can introduce a few shape types at a time.
• What comes in the Polydron School Geometry Set box?
  The box contains 268 pieces: 266 Polydron shapes and 2 Polydron protractors. The shapes are 80 equilateral triangles, 40 right angle triangles, 60 isosceles triangles, 24 root 2 triangles, 30 squares, 20 hexagons and 12 pentagons. Polydron gives the boxed size as 46 x 36 x 13 cm and the weight as 5 kg.
• Is the School Geometry Set compatible with other Polydron sets?
  Yes, the Original Polydron School Geometry Set is compatible with Crystal Polydron, Polydron Frameworks, Polydron Bridges and Polydron Engineer. Schools can combine it with existing Polydron sets for bigger builds or more pupils. All pieces use the same snap-together hinged edge, and each square measures 7.3 x 7.3 cm.
