Juxtaposed Collage Cityscapes - Successful third grade sketchbook lesson with slideshow!

I am in the middle of a unit on Chicago Cityscapes with my third graders.  We finished up our sketchbook project, "Juxtaposed Collage Cityscape," and I am super excited about their success!

To start, students cut out photos and drawings of buildings in Chicago.  They practiced overlapping and constructing a cityscape.  Next, we watched and discussed my little slideshow called "Juxtaposed Cityscapes."  Kids were then asked to draw something in their cityscape, that maybe wouldn't normally be there.
Next, students traced their drawn images with metallic markers, and used opaque paint markers to color.  If time allotted, students colored their buildings with color sticks.
