I cannot take credit for this discovery. My wife actually sent me the link, but here is a QR activity for counting to twenty. One has a St. Patrick's Day theme while there is also one for anytime of the year.
Students count the number of shamrocks on a page, and check their answer through using a QR code Scanner. The teacher even supplies the directions on how she went about setting up her lesson. Isn't it terribly nice when people share their good stuff on the internet? Thanks Mrs. Nelson!
If you are not certain what a QR code is, download this app and use it to scan the code in the picture below.
Enjoy your St. Patrick's Day!
