The following activity allows you to place questions in a math center (or throughout the room/school for a scavenger hunt; or simply print as a worksheet) to practice angle skills. Students use a free scanning app (there are many free ones out there for phones and tablets) to scan the QR code next to each practice problem to get immediate feedback on whether their answer is correct or incorrect.
Included in this download:
20 Angle question cards (with QR codes), student recording sheet, and answer key. This activity could also be completed without the use of technology.
