From June 20 to 29, children will be encouraged to work with architects to design and make their own structures. In Dallingon school in east London, for example, under-11s will visit an architects' studio to design a bridge which will later be assembled in their playground using recycled materials.
A website offers teachers ideas for playground activities such as making a model construction like the Eden Project or the Geodesic Dome out of newspaper and masking tape. One Year 5 pupil said: "It was good to work in a team and make something out of things you normally throw away - it's like we made something out of nothing."
The website also offers children ideas for games and puzzles.
