This was a multi-faceted project that took itself in a different direction than originally intended - I love when that happens! It started as a lesson in value, and mixing paints to make a whole palette of various tints and shades of the same color. Our "palettes" are just pieces of wax paper. Typically, I have students use little foam plates for mixing colors and we just rinse and re-use them. However, this time, I realized it wasn't very time efficient for the amount of mixing they'd be doing in 45 minutes. It worked great - clean up was so easy!
Next, I asked the 5th graders to paint a piece of paper with all the tints and shades they mixed. They only had the one class period to do it, so they couldn't think too hard about what was going on the paper! I encouraged just lines and shapes.
They next class, they explored various ways of cutting up the painted paper and gluing it to the black paper to start a collage. Some students chose to build their collage 3-dimensionally.
I also encouraged them to incorporate any of the "odds and ends" from around the art room; fabric, beads, pipe cleaners, yarn, etc... They could only use objects that fit into their monochromatic color scheme, though! Some students also added finishing touches with metallic sharpies.
