My first graders love using task cards as a math center; especially since QR codes are involved! QR codes instantly make activities more exciting and engaging for all learners. Students are able to check their answers on their own giving them instant feedback on their work. Instant feedback helps students to practice skills correctly which is just one reason, as a teacher, why I love students working with QR Codes.
To access the QR code on each card you will need to download a free QR reader
