I found this lesson on Artsonia. It looked beautiful but when I read the lesson plan, it said three 60 minute sessions. I rarely do extended projects because I do not have room to store them so I modified it.
I was able to do this lesson in one 60 minute session. The students used 9×12 black construction paper. I have paper heart templates they could use or they could draw their own. I showed them some images of Jim Dine’s work and discussed the artist. We reviewed tints and shades then we jumped right into the coloring of the heart.
They first drew a large heart in white oil pastel in the center of their paper. They used a ruler as a straight edge to divide the heart and the background into segments.
For each heart section, they colored in a little more than half using a bright oil pastel. They colored the other half of the section white then blended where they met in the middle creating a tint.
For the shades, they used the same method replacing the white oil pastel with a black oil pastel. I encouraged them to use black closer to the heart so that the image would pop off the page.
