Get on your soapbox
Pupils aged eight to 14 and their teachers can pin notes expressing their opinions and concerns about what is important to young people.
The boxes will be dismantled at the end of July and sent to schools, which will return them for an exhibition next year.
The scheme is accompanied by a teaching pack, and the whole event ties in with the London Literature Festival, which runs until July 12.
