Gordon Hamilton of Math Pickle recently posted these videos on how to make algebra 1 puzzles on rectangles. As I was watching, Kitten came in and looked over my shoulder. She said, “Those look like fun!”

They look like fun to me, too, and I bet your beginning algebra students will enjoy them:

- Single Variable Algebra on Rectangles
- History and Algebra Puzzles (part 2)
- Squaring.net collection of rectangles tiled with squares, sorted by size ratio
