Materials:

• Paper--for practice
• Oaktag--9-inch x 12-inch file folders work well
• Clear tape
• Glue (glue sticks work well)
• Pencils
• Old travel magazines
• Scissors
• Markers
• X-Acto knives

Find several buildings or building details in the video segments featuring area archictecture.

Decide on the basic shaped and size of each building. Is it a square or rectangle? Is it short, tall, wide, or narrow?

Use practice paper first, then transfer your ideas to oaktag.

Make a pop-up street scene!

	Make a book fold in the paper by folding the sheet in half.
	Mark 2 or 4 cuts on the folded edge; cut and crease tab as shown and return to flat position. Open paper to the flat position.
	Push table to inside of folded page (reverse the crease). Try to avoid any part of the pop-up showing beyond the edge when the paper is in the folded position.
	The top of the building (dome or other decoration) may also pop-up. Draw in the detail; use an X-acto knife to make a slit so scissors can cut around the shape; fold into "up" position.

Open page. Flatten paper and make the surface decorations and textures with markers, crayons, pens and other drawing tools.

Suggestions:

1. Take a second sheet of oaktag, a different color, if desired; make one bookfold, apply glue around outer edge; position it as a cover for the pop-up, so the holes don't show.
2. Take several streets and combine them into a Pop-Up City Book.
3. Build a free-standing pop-up city on a larger base by gluing buildings to the surface and supporting them easel-style with a triangle of oaktag (see examples below).
4. Make a pop-up of the buildings in Changing Scale for a vivid example of how Pittsburgh's scale has dramatically changed over 200 years.
