This product has been developed through extensive consultation with education experts around the world, aiming to foster students’ creativity and early STEM skills. This 322-piece Polydron set has everything needed for budding engineers to recreate eight significant bridge structures, from cantilever to cablestay, whilst also offering the flexibility for students to experiment with their own designs.

Quality materials

The durable, classroom friendly, plastic pieces are joined using a reliable clip hinge on the shape edge. A variety of specialised pieces, like struts and pulleys, can be used in conjunction with basic shapes to create impressive constructions.

Easy instructions

The instructional work-cards guide students through creating truss, suspension, cantilever, drawbridge, cablestay, swing and bascule bridges. Students are challenged to plan and build their own bridge structures, competing in small groups to see whose creation can bear the most weight. All eight bridge designs can be made at the same time with this comprehensive set, allowing for whole class involvement and visual comparison between the key elements of each. This set is compatible with the entire Polydron range, and will complement existing school supplies of this nature.
