This is a scavenger hunt using QR Codes based on decimal operations. The students scan the QR code and read the word problem. They solve the word problem and find the answer around the room, which will lead them to scan another problem. This is a great way to review all 4 decimal operations, word problems, and incorporate technology. There is a sheet for the students to record their answers and an answer key is included. This aligns with the 5th and 6th grade common core math standards on decimal operations.
