Another MNPS art teacher showed me this project several years ago, and I really liked it. I tweeked it a bit here and there, but it is basically as he showed me. The students LOVE IT! I do this with 4th grade, but I guess you could try it with other grade levels. All you need is paper, Sharpie, and colored pencils!
Start by drawing a curve line across the paper. Think rolling hill...not roller coaster!
Add 8 dots across the line. They could be(should be) at different lengths apart. You need a dot at realtively close to the edges of your paper.
You will then start connecting the dots. The dots close to the edge will go off the edge of the paper to an imaginary dot. You can not cross over any lines. However, you can share a line as you begin going up and out. The lines should be taken off the edge of the paper as you extend outwords. Some sections may be pinched off as other sections grow larger...and that is totally ok.
This is a students work that's a great example of what it should look like. The students should pick a group of colors they feel work well together. The will press harder in the corners...and as they near the center get lighter and lighter. This is a great way to get them practice with pressure control!!!
