This QR activity is an exciting way to review fourth grade base ten concepts. Students will find the phone that says “Start” and scan the QR code to reveal your first question. Figure out the answer and look for the phone the displays that answer. Then scan the QR code below it. Each time you scan a new code, it will lead you to the next phone.
This product was designed to address all of the 4th grade Common Core "base ten" standards (4.NBT.A.1, 4.NBT.A.2, 4.NBT.A.3, 4.NBT.B.4, 4.NBT.B.5, 4.NBT.B.6)
You'll need an iOS device or other smart device that can scan QR codes. Enjoy : )
