A full set of comprehensive work cards will help to guide the user quickly and efficiently. One of the unique points about this new and innovative set is that the pieces are completely interactive with Polydron Original and Frameworks pieces, and so will complement all existing classroom stocks. A must for any design and technology class. ▶▶ Lots of new engineering components included ▶▶ Totally unique D & T product that provides clear links between maths and engineering ▶▶ Supplied with work cards ▶▶ Fully tested by schools and experts

What the experts say: “A superior educational building kit.” Parents Choice organisation, USA.

“It’s surprisingly difficult to find gear wheels with teeth in simple ratios. Polydron have such a kit… and you can stack wheels to produce gear trains.” Paul Stephenson, The Magic Mathsworks.

To aid easy assembly all Polydron sets have at least one Frameworks piece

Original and Best Polydron is the original and still superior construction shape, recognised in many countries as the world’s leading resource for teaching Maths; two and three-dimensional geometry; design and technology. It is used as a major aid for developing spatial awareness and is easily used by children, giving excellent play value, although it is versatile enough to be utilised for complex mathematical theories.

The unique joints readily snap together giving a superior hinge. This design is critical to forming two and threedimensional geometric shapes. The range is fully supported by an assortment of professionally written books and activity ideas. The tough and durable pieces are made to a quality which will last and be relevant for generations to come.

There are 3 inter-changeable systems: ▶▶ Polydron – Original and Best ▶▶ Frameworks – Open framed Polydron ▶▶ Sphera – Spherical Polydron ▶▶ Fully supported with literature ▶▶ Tough and durable ▶▶ Educational and fun

Polydron Books Written by education professionals to support the mathematical application of Polydron in the classroom, these books include lesson plans, photocopiable exercises, glossaries and fun activities. 10-0144 Using Polydron Book 1 10-0145 Using Polydron Book 2 10-0112 Mathematics with Polydron

Frameworks

Mathematics ®

Open framed Polydron Frameworks is the next generation of Polydron with the versatility for bigger and more complex shapes. A unique joining system makes Frameworks completely compatible with original Polydron which will complement any packs already in the classroom. Frameworks is lighter so the user can construct more complex and adventurous designs that allow them to see inside of the shape, and explore the space within.

Frameworks is equally versatile when used independently and will help learners to investigate and understand shapes, angles, edges, vertices, planes and tangents. All sets are accompanied by a booklet to help teachers understand how Frameworks can provide a wide range of stimulating learning experiences for their pupils. An excellent addition to any classroom which will benefit children from age 6 upwards.
