The term "Pop-Up Adventure Playground" is a term that is free for anyone to use, as long as they are working within the principles and beliefs of the meaning. the idea is to remove barriers to child-led free play, inspired by the principles of playwork in the UK.
I read about this via let the children play - always a great source for information. Her post will give more information about similar initiatives in the UK and Australia.
I'm buzzing with ideas about how this can work where I am. Have you ever seen anything like this?
