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.

Couldn't stop playing

My 5 and 7 yr olds both loved this game. It has just enough fun mixed with learning. Kids loved earning new hats. Problem solving mixed with math and physics was also great
