Great practice for rounding!! About 80 different QR codes to practice. Includes rounding to the nearest ten, hundred, tenths, and hundredths.
In the download I have included the answer, QR code, and "question" for the student to have to figure out before checking their answer with the QR code. When I gave this to students I cut off the answer. (Or, you can simply fold the paper if you trust your students will no look at the answer!)
Could be used at a center or just for additional practice when you have some extra time.
