A review game

This post is dedicated to a game that I title "around the world."  This gives chance for kids to practice/review skills and move about the room.  It works best on problems where students have been given some practice, but are still in need of practice before they are ready to formally assess.  Let us call today a good day filled with formative assessment! (I once did this using ACT practice problems.  It was a train wreck!)
We were working on radicals: simplifying, operations, and solving simple radical equations.  Instead of a 15 question worksheet, I created this game "around the world."  Using the 15 questions (or so) take 15 construction pieces of paper and fold them in half.

Front of cards - the answers.

Put the question on the inside of the card and put the answer on the front of a different card.  Repeat.  Then use tape to post the cards around the room.


Students will start at any card, raise it to get the question.  They answer it on their own paper and proceed to walk "around the world/room" to find where the correct answer is on the front of another card.

Picture of two students enjoying around the world!

Picture of student groups working.  One is raising the card to get a new question.

It has built in checks!  If they don't see their answer, then they know they are wrong and need to check their work and try again.  I usually let them work in a partner pair for this activity.  A group that completes will finish the loop and come back to their first card.
In my opinion, it doesn't really matter if they finish or not.  A slower student who shows careful work and is able to successfully complete 7 questions correctly is a successful day; just as a student who is able to complete the loop.
Does anyone have another fun way to get kids moving around the room while getting in good review/practice?
Thanks in advance for the feedback!
