This is a lesson that we worked on before the Christmas break and into January. We did two point perspective with just a simple house. This was a good way, not too complicated, to introduce perspective drawing. 
We walked through the steps as a class, which helped to keep everyone at the same pace.
Once the house was complete, the kids turned them into gingerbread houses, so that they didn't look so cookie cutter.
This lesson was done with both 4th and 5th graders, and both grade levels really struggled with using a ruler. The kids just don't use ruler enough to know how to use them correctly.
They were able to choose how to color their pieces, but many did sunsets and aurora borealis.
These took two art classes to draw the house (with lots of time going over how to hold the ruler), and 2-3 days of adding details and coloring.
I would say that this was a little bit of a challenge for many of the students, but they were really proud at the end once completed.
