I had middle school did several different kinds of perspective. Each grade did a different style to vertically align and build as they got older. Check out the list and links below for the full lesson and steps on the project.
7th grade: 1 point eye level city or countryscape
8th grade: Cityscape from 1 point birds eye
Next year I hope to move these all down a grade and have 8th grade do 2 point perspective. This is all in hopes to aid the High School Art Program.
