I have borrowed an idea from the mflresources group, and created a sheet for all members of staff to use on Friday to celebrate EDL. Basically it is a competition for them, as they will use a word or phrase or even phrases during the day, and pupils will initial their sheet when they hear them. The most 'merits' (initials) will win that teacher/staff member a prize. Just something to raise the profile of languages and for all to have a bit of fun. It's all explained on the sheet.
I've attached the sheet. You should find it over on the mflresources group too, with an acknowledgement to the original mastermind of this idea!
