Construction Blocks
The Construction Blocks kits are a great resource for free construction play or themed creations. Please check the details for each set as they are very different kits.  
 
Plastic blocks 
The Plastic Blocks collection is pretty big.  
 
Better blocks (3 crates, 11kg)
BetterBlocks were an Australian made alternative to Lego. They sold over 2 million sets with the distinction that they were flexible and could bend to make curves.
 
We have 3 crates packed with 11kg of assorted BetterBlocks for many hours of construction fun and challenges. Simple construction blocks are a great way to model almost any topic.
 
With 11kg of blocks there are enough blocks for each student to have their own pile or to cover a large floor area.
 
MEGABLOKS (5 crates)
MEGABLOKS are from Canada's largest toy company and the world's second biggest manufacturer of construction toys. Our collection covers 5 crates, with (at the time of writing) 2 crates of mixed pieces and crates of yellow, green and orange pieces.
 
These are very common constructions blocks selling in most department stores. This kit gives you enough parts for a major construction project or many smaller projects.
