Kindergartener Learned to Add Fractions!

Fun, engaging app for introducing fractions! I was skeptical before purchase, but the reviews were so good that I gave it a try. My kindergartener tackled the app with relish. Within three days, she had completed all the levels and had a basic understanding of fractions. She doesn't know the mechanics of adding fractions with unlike denominators nor reducing fractions, but she does understand the basic concept of how 1/8 plus 1/8 equals 2/8 which is 1/4. She also understands 1/4 plus 1/8 equals 3/8. Amazing!
Even after she completed all the levels, she happily went back to the beginning to work thru again!

This is far and away the favorite app of my four-year-old son and seven-year-old daughter. They are talking about fractions all the time, they created a paper based version of slice fractions, and my son asked Santa for a hat with a flashlight : just like the elephant. So to say this app has been a major driving force in our house for the past few months is an understatement! Great job Ululab: this is great and your latest update is incredible.

Lots of “aha!!” Moments

This app is fun and educational at the same time. The game does not distract from the learning. End it actually gets pretty difficult when it gets to the comparing fractions area... although my son started playing this a few years ago at age 6 he would be challenged still - as the app continues on... going through all of the aspects of learning fractions.
I secretly love to play it too!!!
