Talk about bad timing. Our 'ALL CALL' system, which allows me to make announcememts to all the rooms in school at once, has quit!
We hope to get it fixed before the conferences start tomorrow night, but otherwise I will have to call every room and then "next" or "times up" maybe all I have time to say!
Thanks for all the suggestions, some highly amusing and some very good. I will let you know how it goes down :-)
BTW - having a hectic week what with the above looming, so haven't been out to play in blogland much. But I appreciate all your visits greatly and will be doing the rounds by the weekend and catching up with y'all.
