One to Eight
Prepare a piece of paper with dimensions 2×4, then fold it four times to form 8 squares. Write on the squares in the top row the numbers 1, 8, 7, 4, and write on the squares in the bottom row the numbers 2, 3, 6, 5.
Now your task is to fold the piece of paper several times, so that the squares end up on top of each other, with the numbers appearing in ascending order top to bottom, and 1 face up.
Once you do this, try again with numbers 1, 8, 2, 7 on the top row, and 4, 5, 3, 6 on the bottom row.
