I wanted to make something to use as a get to know you/opener (of course using QR codes) for the class, so I created a Dynamic Duo QR Code Activity. This can be used with all grade levels as well as adults. I also included blank numbered cards that you can add your own pictures, QR codes, etc.
You can find it here on TpT!
I also placed all the red and black number sets you have seen in my previous classroom reveals into a FREE bundle set on TpT...finally!
ENJOY!
