Kids keep asking to play!

I use this app with my 4th and 5th grade students on my classroom iPod Touches. They keep asking to play this game and love beating their score from previous weeks. Besides giving good fractional number sense and using number lines, when a student gets something wrong, it scaffolds and gives them more clues to get it right the next time. In that sense its a mini-teacher.
Only complaint is that since we share the iPods, they wish there was some type of log-in or way to save their progress from previous times. It would build better off of what they know, rather than start again from the beginning. Also, kids that have gone through many levels are looking for the next challenge.

Otherwise, all great things to say about this app! Its addicting! :)
