App Friday: Long Division & Column Addition by iDevBooks

Welcome to App Friday, our weekly link exchange of family-friendly apps. This week Esa from iDevBooks is featuring two of his math apps: Long Division, and Column Addition. Inspired by his daughter’s need for a math addition app, this Dad developer from Finland utilized his computer science background to develop his own homework helper. Now there is an entire series of math apps from iDev Books on the iTunes App Store – it’s all adding up!

What are your apps about? My collection of 17 math apps can be used to teach and study different pen and paper algorithms.  I have a background in researching, designing and developing visualizations of complex computer science algorithms. I developed my first app, Column Addition, to help our own daughter learn column addition. In addition to algorithm apps I also have a Fraction Math app.

Long Division by iDevBooks

Long division can be a struggle even for adults, but with the Long Division app practicing long division is easy and fun. The app can be used to practice long division with 1 or 2 digit divisors and up to 5 digit dividends with or without decimals. Remainders can be allowed or disallowed. When dividing decimal numbers the app will add zeros to the dividend when needed.

Column Addition by iDevBooks

Column Addition app can be used to practice column addition. There are no penalties for wrong answers and nothing bad happens no matter what the user does. When the user solves an addition problem he or she will get one more piece of a jigsaw puzzle. Every aspect of the app can be customized, including colors of the interface, speed of the animations, difficulty of the problems, etc.

Why are they special? My aim in designing the apps has been to keep things simple. My apps are ready to be used immediately, there are no instructions and none are needed. Wrong answers are never penalized, there are no counters timers or any other distractions, and custom keys – to make inputting even 3 digit numbers a one-tap gesture – have replaced keyboard. There is a speed setting that can be used to make the animations and other transitions as fast or slow as the user wants.

Schools and parents are using the apps to aid teaching algorithms. Some schools use the apps to tutor students who are struggling in math. All of the apps have extensive settings that are always only one tap away and can be used to set the difficulty of the problems, colors of the interface, and other settings.

What’s in it for me? For App Friday November 12th, Esa has set Long Division and Column Addition to FREE on the iTunes App Store. Apps usually revert back to regular pricing by 8pm US Pacific Time on Friday, so download quickly!
