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.
