Division.....Division

We have been working on division for the past 2 weeks.  I think my students are tired of division, but they just don't have the mastery that I am looking for.  Time to think of something fun to do......Mmmm something with food perhaps.  I will have to think some more.  Let me know if you have any cool ideas for teaching division.  I did try one thing yesterday that the students really enjoyed.  I had them get into groups or partners.  Each of them had to create a problem for the other one to solve on the marker board.  After each person solved their problem, they got to check it with a calculator.  Gasp...  My students thought that was the coolest thing.  I don't know if it was the calculator or getting to solve a problem that their classmate had given them, but it worked.  I will definitely be doing that again!
