I think I can help you a bit. I too had to teach one-point perspective to
4th graders, inculding learning support! Challanging, to say the least! I
would definitely use a video on the technique early in the lesson and I also
would use a grid under their papers if you're worrying about a final outcome.
It can be attached with a little bit of drafting or masking tape and it helps
keep their horizontals horizontal and their verticals vertical. They were
experiencing some frustration so I opted for their names as subject matter.
It kept them interested and they weren't as concerned about it looking
realistic. They then chose a color scheme ( cool or warm) and used markers
to add color. Finally, they used fine point permanent markers to finish them
off. They will be done this coming week and most of them look good enough to
Hope this helped.
