Last week, my fourth grade students drew tiger lilies, a lesson from Mona Brookes' Drawing With Children.
I didn't do the lesson as written because it calls for markers, and we didn't have markers. Instead, I had the children use crayons (yellow orange, orange, and red orange, and green yellow, yellow green, and green, and the purple of their choice). They also used fine-tipped black felt markers for the anthers and filaments, and for the black dots on the petals.
To prepare my students for this lesson, I explained that, in real life, things don't have black outlines.
We also discussed negative space and the children did the negative space activities in Brookes' book:
Next, using their three green crayons, they did these shading exercises from Brookes' book:
And they turned out beautiful work.
had students do a purple background for a triadic color scheme.
After the children had completed their drawings, they were all pleased with what they'd accomplished.
If you're looking for a book to help you teach drawing to an elementary schooler, I highly recommend Drawing With Children.
