I'm only including one idea today as I have problem downloading the other photos. Notice the special clip-like thing that was inserted into the hard cardboard. The clip actually kept the accordion cards together (like a frieze), which was retracted or pulled towards the reader horizontally and returned or put back in the same manner. Number 9 card was the one that was visible before being pulled out and Number 1 card was the last one close to the board after being pulled out.
I'm impressed with all those presentation skills that nowadays students can think off! Creative!
