My students absolutely loved the opportunity to check their own work using QR codes with this activity. Students simply scan the code with a QR reader app on a mobile device with a camera such as a phone, tablet, or laptop. When they do the correct answer magically appears! Answers even have the proper regrouping shown to help them more quickly identify any errors. The best part is that while students self-check you are freed to help students who need it.
