Teachers we're using paint chips to test sight words and math facts. I decided to put my own musical twist on it. Instead of words, I used different rhythms. The students are to match the rhythm to the correct time signature. You will need to put all the time signatures you want to test on one paint chip.
I also found this unique Better Home and Gardens paint chips at Walmart with a hole in them. If you get these you could play "Find the missing rhythm." Students have to put the hole on top of the rhythm that completes the measure correctly.
