Folding Paper - Back to the Geometry Puzzles
Divide a paper into 8 sections and write numbers on it according to the picture. Your job is to fold it where the lines are so that the numbers are sorted - number 1 will be on the top, 2 under it,..., and the last one will be 8.

Here is a representation of the solution:
fold-1to8.jpg[/attachment:3679e]

1) fold on the diagonal of 5-7, to put 4 under 6
2) fold 5, and manage to fold it inside the previous fold
3) fold 6-7 under 8-3
4) fold 1-8 under 2-3
5) fold 2 under 3.

All the numbers are ordered, but some of them are fold in 2 on their diagonal (7 and 5).

For the second one, this is the solution (without drawing):
1) Fold 1-4 under 2-3 (5-8 are fold in the middle, so you now see only half of 8 and half of 5)
2) Fold 8-2-7 over 5-3-6
3) Fold 8 under 1
4) Fold 6 and 7 between 5 and 8

Hmm
I don't agree that folding the numbers in half are acceptable.
I have come up with solutions for both that have ALL numbers flat.

Also, I find it easier to work with if you have a peice of paper that has the numbers on both sides (but mirrored of course so that it makes sense)

Here's the first
1: Fold straight down the middle so that the 7 is behind the 8 and the 4 behind the 1 etc.
2: Fold the 1 and 8 behind so that the 2 and 3 are now on the front
3: Here's the tricky bit... Lift the 2 so that you can see a gap between the 3 and 6. Fold the 4 and 5 into that gap and flatten the whole thing.
4: Now simply fold the 2 and 1 over the 3.

The second is a lot trickier but again is possible with all flat sides.
1: Fold straight along the center so that the 4 comes UP in front of the 1, the 5 in front of the 8 etc.
2: Now fold the 4 and 1 onto the 5
Here's the confusing bit. But I promise, it does work.
3: Take the 6 and 7 and put it between the 4 and the 1 and keep pulling it through between the 5 and the 8. The 2 and 3 should follow and stay between the 1 and 2.

There are solutions that are actually much easier than the way you've described them.

The first one can be done in this manner:
1. fold down the horizontal axis so that the 2 is under the 1, 3 under 8 etc.
2. fold in half again along the vertical axis this time. so folding the 7 & 4 under the 1 & 8.
3. then fold the 8 under the 1.

For the second one:
1. fold down the horizontal axis again.
2. then fold each number behind the other. so first the 7 will go behind the 2. then the 7 will be behind the 8 and the 2 goes behind the 1 and the 8 will be on the bottom.

Here is a representation of the solution:
<!-- ia0 -->fold-1to8.jpg<!-- ia0 -->[/attachment:3679e]

1) fold on the diagonal**************no diagonals allowed!!!!***************** of 5-7, to put 4 under 6
2) fold 5, and manage to fold it inside the previous fold
3) fold 6-7 under 8-3
4) fold 1-8 under 2-3
5) fold 2 under 3.

All the numbers are ordered, but some of them are fold in 2 on their diagonal (7 and 5).

For the second one, this is the solution (without drawing):
1) Fold 1-4 under 2-3 (5-8 are fold in the middle, so you now see only half of 8 and half of 5)
2) Fold 8-2-7 over 5-3-6
3) Fold 8 under 1
4) Fold 6 and 7 between 5 and 8

So the instructions are "Divide a paper into 8 sections and write numbers on it according to the picture. Your job is to fold it where the lines are so that the numbers are sorted (number 1 will be on the top, 2 under it,..., and the last one will be 8)."
basically the only rules are, you need to draw it like the picture, we can only fold it on the lines and we need to put it in order. I solved this by
