Congratulations, Carol! Here is an equivalent fraction game for your 4th graders! By the way, I do realize it is girly, so once I finish fulfilling the other winners' requests, I'll work on a boy-friendly one, too!
I hope this is along the lines of what you were wanting!
Just print on card stock (print the last 4 pages twice), laminate if desired, cut, and it's ready! For some reason, the last page was saving strangely, so I had to put 2 on one page and 2 on the other. Weird!
