I explained it to my Grade 3 students like this: they don't all look alike or think alike. If they sang the same song, they wouldn't all sound alike and if they all wrote a short story, it wouldn't all be the same. So why should their artwork all look alike?
With that in mind, I am teaching my Grade 3 kids a skill-how to draw using One Point Perspective-and it is up to them to apply that skill to a product of their own choosing. I taught them how to use their ruler to create parallel lines, as well as using a vanishing point and horizon line. I've also showed them some examples of drawings that use One Point Perspective. Now it is up to them to choose what they would like to make.
I'm hopeful that, when I display their artwork on the wall, we won't have 22 versions of the same exact thing but 22 different and personal drawings using the same skill. I'll post the end results here when I have them, so stay tuned!
