I am a teacher checking out the site for my students. Love this exercise Fractions On A Number Line 1, but I just got 5/6 four times in a row, and looking at The Next Ten Problems I see 5/6 1/6 5/6 3/6 3/6 3/5 2/5 1/6 2/5 1/6 Wouldn't it be pretty easy to stick a check in so that you don't get repeats (or at least not within 5 questions of each other)? Add 1/8ths or 1/10ths if you need a few more options.
