There was no math warmup problem today. I put the 1990s up as the windows wallpaper and then turned on the SmartBoard. They were fascinated. It seemed a hit so I printed them out from the folder - in Windows, you can print some of the contents of a folder and it will automatically scale them to full-page -- and lined them up on the wall outside my door. Teachers thought it was a hoot. The person with the most solutions? The science teacher across the hall. The second best? A senior with a Netflix connection.
Feel free to put in some answers in the comments. The artist's website is cool too, but there are only solutions for the 80s and 90s up so far.
