I submitted Fraction Builder to iTunes yesterday and it was approved in less than an hour! It is so amazing to me what great service Apple offers to developers. I certainly appreciate the way that the App Store provides access to my work to students and teachers all over the world.

In most of my math apps I try to make them icon-based so that language skills are not critical for working with concepts. Fraction Builder has a series of icons across the top of the screen. Tapping each icon results in a specific function.

For example, tapping the red dice generates a random fraction. Denominators range from 1 to 12. Once the denominator is set, numerators can be any number that results in a proper fraction.

When the question mark is tapped, a question is generated and displayed on a moveable note. To answer the question students drag number tiles to make the fraction. Usually it is best to start with the denominator. If using this app in a classroom, the teacher should explain that the denominator represents the number of equal parts. For this example, the student would first slide the three tile to the denominator position. Next, the student should slide a one to the numerator position. Once the numerator and denominator have been properly set, the students should tap the check mark. When this icon is tapped the app compares the students answer to the correct answer for the question.

A scoreboard displays student progress as they work with the app. It shows the topic, number of questions attempted and the percent correct. Quiz questions are based on three main topic areas:

• Naming Fractions

• Equivalent Fractions

• Comparing Fractions

Various other functions are performed when other icons are tapped. This chart explains the other functions.

I hope that teachers will let me know if they are interested in evaluating this app for use at their school. I have a limited number of download codes for FREE evaluation copies of this app. For some students learning about fractions is difficult. It is my hope that this colorful interactive app will help them in their journey to master fraction concepts.
