I created a review game, using Snakes and Ladders. A smartphone or mobile device with a QR-code reader is required. There are 60 area and volume problems to work on (if you don't like the game). The answers can be obtained by scanning the QR-code.
The volume problems include the method of disks, washer, cylindrical shells and cross-sections.
Since I also use this for my own classes, the links from the QR-codes will remain in place. I am in the process of creating more of these for my other classes. If there is a topic that you're interested in, please let me know, maybe I have it in the works! =)
If you encounter any problems with the cards, please send me an email! MrsCarlsonCHS(at)gmail.com
