My students LOVED this lesson. Perspective is part magic and part math and for creative types like me, there are specific rules that really work. My students discovered these as we worked through the lesson. About half of my fifth grade class finished this lesson in three, 50-minute sessions. The other half need an additional 30 minutes to finish.
Perspective is everything, especially when it comes to drawing the background for my characters front cover. Using this I managed to draw a city background with amazing proportion and my character jumping through the air.
