Freebie Version: Includes 2 worksheets of addition to 100 with QR Codes.
Full Version: Includes 6 worksheets of addition to 100 (and some with "a little bit more," slightly over 100, as students have difficulty transitioning to numbers like 101, 110, 111, 121, etc.). All of these have answer keys for easy grading and for those that do not have devices available for QR Code use.
QR Codes are great for motivating students, so they can get to use technology. Just download a QR Code scanner on an iPod, iPad, or other device, such as i-nigma or Scan. Open the app, hold it over the QR Code (looks like a bar code, with a bunch of squares), and students can check their work.
