Pros and cons of Oh No Fractions! - Curious Hat Lab app for iPhone and iPad

Oh No Fractions! - Curious Hat Lab app good for

I recommend this app for all the parents! Its a easy way to learn things for the kids!

This is a great app. Fun and easy to use. If you have truouble about fractions, no matter you are a kid or adult, this is the app you should get.

Some bad moments

Had a great time with my little cousins playing with this app!

Nicely done app - provides a clear visual model for comparing fractions

The whole point of apps is to be more entertaining than just solving problems in a book. This app is just so boring and doesnt make fractions any less painful for kids.

Def could help a kid practice comparing fractions and building some number sense. Too many of them are equal to a whole such as 12/12. Maybe add a difficulty meter?

this sweet, super fun math tool really drills you on fraction comparisons. whats neat is that once you learn the peek visualization, you almost set for life when running this in the minds eye. Try setting it to 99 divisions; then you’ll run into some real close cases to test ones acuity. Insider scoop: theyre working on even more fun version adding fraction addition, subtraction, multiplication and division plus improved stats. Super cool super fun love the elevator peek solver. Foob

Its good and educational but they could have made it more interesting so that kids would actually want to do it
