Students love moving around the room to work on math problems. Checking answers with QR Codes is an added bonus!
Hang each of the 10 problems around your classroom. Give students 2 – 3 minutes to write their first equation in slope-intercept form. When they move to the next problem, they can check their previous answer using the QR code. Continue until all 10 problems have been completed.
Two different recording worksheets have been included. The first one is blank. The second worksheet includes the problems. (This is great for absent students who need to make up the assignment.) Some teachers like to have students work on the problems at their seats, then move to check their answers using the QR Codes.
