Yes good of someone to ask us supply teachers. Looking at the original post I would be flapping a bit it I needed to deliver a Poster and a Flim in the same lesson. I would be flapping around with the electronics then having to flap around with the resources for the poster. I am not MFL but I can handle German but it rarely comes up these days. However if I am in a subject I really do not have much to contribute such as French or Spanish. Then I prefer simply text books and the page and exercise numbers. And does the teacher want the work completed in the students textbooks or on paper.
