@lila@octodon.social @jessmahler Fold the paper while the student is touching it, feeling it bend, and feeling the crease form; repeat a couple of times and talk about the nature of folding paper. Then introduce, by touch, another sheet of paper; crimp the edge using the student's hands, or have the student do so. Then take it and quietly fold it in half (maybe quarters) yourself, hand it back, and talk about what must have happened, even though it could not be directly perceived?
@jessmahler @lila@octodon.social Oh, I forgot part of my explanation - crimping the corner is so that the student can feel that this is the same piece of paper, by finding the familiar crimp in the otherwise differently-shaped paper. Other tactile marks would work as well.
