Students will have fun subtracting linear expressions with this scavenger hunt! They will solve a problem on the bottom of a card and have to find the card with their answer to move onto the next problem. The answer will be on top of another card. That card will have a QR code for them to scan which will give them a clue to solve the riddle.
**The expression on the top and bottom of the card do not match up. The expression at the top is the answer to a previous problem they solved.**
