My Primary school is running a one week learning festival the week before half term during which my brief is to teach twelve classes of roughly 30 mixed age (year 3 - 6), mixed ability classes. Should be interesting given the vast difference between the most and least able.The remit is the learning should be very much pupil led and I have between 40 minutes and an hour to make it happen for each class. I have limited workspace beyond my music room, probably no TA support, I wont have access to our IT suite and probably no access to the video equipment as this had been commandered for a media project. If the weathers good I have some outdoor space. So my initial thought is a one off junk piece. Start with a video clip of something cyclic and let the more able lead the composition of a class piece. Zubaddo from Music Express springs to mind. Any other suggestions on a postcard please.
