1. Fold a piece of paper (12" X 18") or other size, in half hamburger style (short way). Open and then fold in half hotdog style (long way). Do not use the top section of the paper. This will be folded down to cover the back of the pop-up page later.

2. Take your scissors and cut a line from the folded edge of the paper to the middle of the paper. In the picture you see a zigzag line. This solid line is cut. You can cut any kind of line you want depending on what you are making. If you were making a shark or piranha a zigzag line would be great.

3. After you cut the line, take the pieces and fold them back (where the dotted lines are). Notice that the dotted line cannot extend into the top section of the paper. You need to fold both the top and bottom pieces back. Fold the pieces back and forth from the front to the back on the same line. This makes a good crease and I tell my students to make it "loosey-goosey". Then put the pieces back flat.

4. Open the paper. Fold the top section down to cover the back of the pop-up page. The paper will magically talk to you and tell you which way it wants to fold down. Put a thumb at the top and a thumb at the bottom of the page. Then fold the page closed and press. You may need to help the form pop out but it should pop out automatically.

This is how the mouth form should look when it pops out. Use a variety of media to add color to the pop-up page. I usually have the students draw with black markers and then color the pages in with crayons/colored pencils. The page can be turned different directions to make a variety of things.
