Number Line

By Todd Bowden

This app is only available on the App Store for iOS devices.


My new app NumberLine2 for iOS7, iPad & iPhone5 is now available. Go to or tap on “Developer Apps” to find it.


Number Line is an educational game app to help students learn about fractions, decimals, and percents by ordering equivalent fractions, decimals, and percents on a number line. The app features multiple levels where the player must drag circles with either a percent, decimal or fraction onto a number line in the correct sequence. A score is earned based on the time it takes to put all the circles in the correct order (faster is better), plus points for each correct placement, minus points for each error.

Wildly addicting

As a teacher of 5th graders, this app is fabulous. The kids love it. It really helps build number sense and relative size. I've seen a big improvement in my students' ability to order fractions, decimals and percents.

Can't get it to work...

I was really excited about this app until I started playing the game. I could not easily move the circles and one just would not move at all. I'm using a brand new Itouch as well. If anyone has a suggestion on how to move the circles better please let me know.

I liked it

I realy loved this app, but I can't move anymore those numbers. The whole screen slides left and right.
