We go to conferences to confer, and Show and Tell, which I first saw at Joe Dale's Isle of Wight conferences over ten years ago, is one of the best ways of making this happen. This year's Language Show Show and Tell was hosted by the London Branch of the ALL and led by Helen Myers, still glowing from her recent and richly-deserved MBE.
Highlights included two verb songs for teaching "aller", and this free app, Vocal Recall, for android and apple. Print off some stickers, and record comments or any language item. Stick it in a pupil's book, label a room, read a pupil's work back to them in the new language, or make a talking book - they play the material back with any smart device. Brilliant!
