Polydron

Polydron XL Geo Dome, 62 pcs

Item No: 57-70-7130
Hand-eye coordination
Shape and colour recognition

Imagine the fun of building castles, cars, tunnels, and boats, as easy as pie. And not just tiny versions, but big enough that your child can play inside them afterwards. Here's the perfect solution if you promised your child a playhouse and are looking for a fun and easy way to make it happen. 

The large construction shapes invite your child to crawl inside, go around, put the pieces together, and stretch up on their tiptoes to put a roof on their playhouse or a top on their tower. Crawling inside the structures to peek out, building tunnels to wriggle through, or competing to build the tallest structure all help develop your child's proprioception.

We often associate building blocks with quiet sit-down play, but with Polydron XL, your child needs to be on their feet and actively move their body as they put the shapes together. That’s why Polydron is a wonderful gift idea, both for little bundles of energy and for kids who love to build and construct but tend to opt out of physical play.

When your children play with this fantastic set, which is also very suitable for professional use, they learn about geometry and symmetry without even realising it.

Once the pieces have been put together, the constructions are quite sturdy. So you can leave your project overnight and come back to it the next day. Unless it’s super windy, your outdoor creations will usually stand strong overnight. Working on group building projects is a great way for children to develop their collaboration and communication skills, as they figure out how to share the pieces and agree on where to place them. 

In this set, you'll find:

  • 30 squares
  • 12 pentagons
  • 20 triangles

Polydron XL is four times larger than Giant Polydron. Do you already have some Giant Polydron pieces, or would you like to add them on to this set? No problem at all - Polydron XL and Giant are compatible with each other.

The pieces have bumps on one side, so children can tell the shapes apart by feeling the textures - great for their tactile sense. Another feature is that the insides of the Polydron pieces have (English) braille markings, which gives children another way of exploring and recognising the shapes.

Polydron is one of our most successful toys in our entire range of educational and developmental toys. It looks simple – and that’s often the hallmark of the most successful designs.

All Polydron products can be assembled freely according to your own imagination or by following the included inspiration guides.

The plastic is lightweight, so it won't hurt if a piece falls on your head. However, the pieces aren’t too light - the wind won't carry off your creation on a breezy day at the playground. 

Polydron XL can be wiped clean with a damp cloth and a bit of mild soap. You can also disinfect the pieces with rubbing alcohol.
The pieces are made from 100% recycled plastic.

Do you know Polydron?

The English toy company Polydron is one of ToyAcademy's oldest playmates. Much has happened since Polydron released its original toys: pieces of solid plastic that can be connected in countless different ways. The original Polydron pieces still exist, and they bring joy to children with developmental and imaginative play in many homes, schools, and kindergartens.

Nowadays, there are lots of other types of Polydron. Maybe you've heard of the magnetic building blocks Polydron MAG, which are also available with mirrors and in models suitable for young children under 3. Also check out our huge XL Polydron sets which are perfect for building extra large structures, and which can also be used outside in the garden and can be passed down for generations. You can actually build a real Polydron playhouse that you can play in. A common feature of all the Polydron variants is that they're really robust toys that can be passed on when your child outgrows them - so they enable generations of curious children to play and learn.
