Makedo needs little introduction; find some cardboard, grab some Makedo tools and get started. The awesomeness of Makedo is that children learn by doing, creating, experimenting, failing and maybe succeeding but that's not essential.
The creations then open the door to imaginative play where the child is protagonist in a hack-able world of their own making.
Find
Makedo is the most open-ended toy construction system ever because the reusable tools work with cardboard; a universally available, free and unlimited building block.

Make
Designed for girls and boys, young and old, individualsand groups of all skill levels. With Makedo you can make anything imaginable of any size from a flower to a fort, a mask to a maze.
Play

Makedo creations set the stage for immersive, creative and open-ended play where the child is protagonist in a hack-able world of their own making.
Use the Makedo SCRU Driver and SCRUs to join cardboard together.
Simply punch a hole through the material, insert the SCRU into the socket on the end of the SCRU Driver, and then with a few quick turns the cardboard will be securely joined.
