Students practice adding 5 digit numbers. Cards can be completed all at once or only a few at a time using the answer sheet to record which have been completed and which still need to be done. Once they have solved the problem, they use a device to scan the QR code to self-correct their work.
(Note: You must have a device (iPad, Smartphone, iPod, etc) that has an app which can scan QR codes)
This card set is included in my MEGA BUNDLE - Get it and all future cards I create for one price. http://www.teacherspayteachers.com/Product/MEGA-MATH-BUNDLE-QR-Code-Task-Cards-982951
