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!

5 Cool Ways to Learn Math with Apps

Our feature this week is from Lynn Rasmussen, creator of Arithmaroo – a math counting game focused on number patterns and relationships. The Arithmaroo team is working on an entire series of educational math apps that engage the user to explore and experience numbers.  Today Lynn highlights the many different ways math is being presented with mobile apps, which makes it an exciting time for students and educators.

Many of us were taught math in classrooms. Everyone was given the same worksheets, drills, homework, and tests at the same time. If you didn’t get it, the class kept going.  Too many of us were either “bad at math” or bored.  Apps offer a solution. They are personal, interactive, and provide instant feedback. Most of all, they are fun.

Here are five ways that Moms With Apps developers apply math to apps:

  1. Apps offer a beautiful introduction to math for little ones.  TickleTapApps’ Counting Caddy is a simple, fun counting game. With their Pattern Painter preschoolers learn to identify shapes and then they learn to draw shapes.
  2. App games are great for practice and assessment. Kids can start at their own levels. Incorrect answers are challenges, not failures. The KidsMathFun series  separates math operations by grade level and replaces grades with wins. They even have an app for Telling Time!
  3. Some apps are real tools that can be applied in fun ways.  Using Percentally kids can tally basketball stats or tally how many times someone says thank you, and then see how tallies convert to percents.
  4. Apps bring math alive. The iLiveMath series is not only graphically beautiful, but their app design and navigation is fascinating. Word problems with gorgeous photos are way more fun than standard worksheets.
  5. Apps offer diverse learning experiences.  Using a “right brain” approach, the Arithmaroo series replaces rote memory methods with increasingly complicated rock and hand patterns, all presented as games.

Apps offer powerful new ways to teach and to learn. We developers are just beginning to explore the possibilities!
