We are developing fun applications that stimulate and inspire children to learn and practice math both at home and at school.

This application encourages Four Grade children to practice the addition of two decimal (0.1-9.9) numbers (with carrying), the subtraction of two decimal (0.1-9.9) numbers (with borrowing, but without negative answers), the multiplication of a double digit (1-25) number with a single digit (1-9) number, and whole number division of a number (1-225) divided by a number (1-15).

Children can gain confidence by doing practice problems with unlimited time, or they can build proficiency by selecting "Minute Math" to see how many problems they can answer with a time limit. The app defaults to 10 problems and 60 seconds, but these can be changed in the SETTINGS area of the iPhone/iPod Touch.

Teachers are using the Kids Math Fun applications in their classrooms to reinforce math, addition, subtraction, multiplication, and division concepts. Considering their comments, we added a “Double Dare” feature so children can expand their math skills by mastering the inverse relationship between addition and subtraction. A “Try Again” feature allows children to develop mastery by attempting a problem again if they get it wrong.

A new “Show Scores” button allows children and parents to see the high scores for all four regular and all four “Minute Math” activities.

A score board in the right hand corner, shows how many addition, subtraction, multiplication or division problems have been completed along with the totals for correct and wrong answers. Graphics include: Smiling kids, kids playing outdoors, healthy fruit and vegetable snacks, boats, and buildings.

Total Practice Problems can be set between 5 and 100 problems, the Minute Math Timer can be set between 1/2 minute and 10 minutes, and High Scores can be cleared.

Please take a look at our other popular apps: Kids Math Fun K-5, Kids Time Fun, and Kids Coin Fun.

The title says it all! Kids Math Fun~Fourth Grade was developed to encourage Fourth Graders to practice their math skills while having fun. We are proud to say this App contains no ads, no in App-purchases, no social media, contains absolutely no links, and no data collection.
