My vision is that after each exam is finished, the following year the "Wall of Fame" is added to with new pictures and new scores. I know this is not a new idea, and I'm sure I saw this idea somewhere before.
I'm thinking that the following may work for me. Some time in the beginning of each year school year, when students are still well rested and fresh, and we're not too into curriculum, I take everyone's picture with a blank placard, something like this:
Then after I see who passed the exam, I print those pictures and write their score with a sharpie .... or HOLD THE PHONES ... I could even edit the pictures, so not everyone has a white ball face (joke).
Anyway, I'm excited about this, and soon the little cherubs will be in my camera roll.
