Using straight lines to create curves

I've been out of school almost 2 weeks, recuperating from surgery. Tomorrow is my last day off and I'm feeling ready to go back on Wednesday. Before my absence, I started my 6th graders on this simple project. A few kids got done before I left and these pics are their solutions. This is so easy and quick and the kids are fascinated with the process. I showed them, using graph paper, how to use repetitive straight lines to create curves.

We simply count dots moving out in right angles from a corner. Then we connect the FIRST dot on one side, with the LAST dot from the other side. Then we move out one dot on the first side, and and in one dot on the other, connecting again. Repeat until you connect the last dot to the first dot! Simple! One you learn the process, there's lots of ways to vary the curve, and combine various curves together to create designs and images. The kids were charged with the task of creating "something". The only rules were to use the straight lines into curves method, and to finish it in a way that it could be hung up for display. They enjoyed the challenge!

I left the sub with lots of cool stuff to do - perspective "flying boxes" with 4th grade, and perspective words with 6th grade,"Not a Box" projects with the younger kids, and much more. I can't wait to see how the kids have done. I promise to take photos and show you!


  1. This brings back memories. I still remember doing this for the first time in either 5th or 6th grade and being fascinated with the results!!

  2. Great to see their thinking on this! Some really creative solutions. . . they will never look at a bridge the same again.
