This was the final art project I did with my Grade 4-6 class this year. We managed to get it completed in two- 80 minute periods. Some boys reminded me they requested an Op art project this semester so I had to quickly find one, lol.
Luckily I found THIS lesson on the website Art with Mrs. Filmore and it worked really well. I definitely didn't explain it well enough and about 30% of both classes had to re-start, some had to re-start 3 times. So I do suggest you have the kids follow along as she does in her video tutorial.
I also pre-drew the first lines as I knew it would take my kids forever to do it correctly and we had limited time. I would say this project took a lot of patience for my kids to complete but they all completed it in the end and were very happy with their results!
These were about 8" x 8".
