Team game to work in sixes. Poster of road signs put up at one end of hall. First cub runs up selects a road sign and memorises, then runs back to six and explains what it looks like (shape, colour, etc) and what it is called for another cub to draw. Cubs then take it in turns until everybody has had a turn at both drawing and explaining. some may need to go twice to ensure same number.
