The app is easy to use and it has an intuitive interactive interface with customizable colors and other settings. The user can solve random or custom addition problems with small and large numbers. The number of digits in the numbers can be set. The column addition method is also known as columnar addition, long addition or longhand addition. Review by funeducationalapps.com: "iDevBooks educational math apps make math enjoyable and entertaining. One of my sons was struggling with math and I must say the use of iDevBooks math apps has really helped him. He now enjoys his math.." Review by professor Tim Pelton Tim Pelton, assistant professor of Mathematics Education at the University of Victoria reviewed the sister app of column addition - column subtraction: “Because no wrong entries are allowed the app provides a passive form of positive reinforcement and your child will likely improve in both confidence and competence with respect to the procedure.” The interface of Column Addition app is similar to Column Subtraction. Endorsed by teachers Rita Zeni, Ecole Sandy Hill Elementary, Abbotsford, BC, Canada: "The Math apps by Esa Helttula allow students to practice and reinforce the specific computation strategies taught in class, with as much or as little scaffolding as necessary. They also provide individualized feedback to each student, with an immediacy that is not always possible through pencil and paper practice. Being able to adjust the level of difficulty to suit their needs is also very motivating for the students. I am so glad to have come across this great educational tool!" Easy to Use The numbers are aligned automatically and the user can concentrate on solving the operations for each column. Carrying is handled automatically and it is visualized using a nice animation. After the user solves the operation for each column the correct answer will fly to the right place. The unit of the answer will fly under the column and the ten is carried over the next column. If the user presses the wrong button the answer will appear above the keyboard but it will not move. 25 Six-piece Jigsaw Puzzles The puzzles are pictures of cute animals. Every time the user solves one addition problem, one more piece of a six-piece picture puzzle is revealed. The picture puzzle feature can be turned off and on at any time. Features: - The user can add 2 or 3 numbers - The app can provide random problems or the user can input his own numbers - Each number can have from 1 to 5 digits - The current operation for each column can be hidden - The operands of the current operation can be highlighted - Colors of the interface can be changed - The speed of the animations can be set - Different interface on iPhone and iPad - 25 6-piece jigsaw puzzles of animals are shown one piece at a time - The jigsaw puzzles can be hidden Other iDevBooks math apps iDevBooks math apps have been reviewed and endorsed by Wired.com, IEAR.org, Edudemic.com, Teachers with Apps, and other respected sites and organizations.

My oldest daughter found it installed on our iPod once and used it to teach herself column addition before I’d even covered the concept with her. She isn’t an exceptionally mathy child, but the visual, process-oriented approach this app takes is superb. It can be used both as a form of primary instruction and as review for children who need more practice to cement the steps of column addition. The visual aids such as highlighting the current column being worked on, breaking the current column down into a horizontal problem at the bottom of the screen, and the carrying animations are all so helpful – particularly to children who might be overwhelmed visually and have a hard time tracking the various steps required to solve the problems. The minimalist design of the app also helps to minimize visual distractions while remaining solidly built. What We Didn’t Like: My daughter has found the puzzles so motivating. It would be excellent if the app were set-up so that multiple users could store their completed puzzles in a gallery within the app to revisit the cute animal pictures at a later date. Overall: Column Addition is a deeply process-oriented math app that supports children visually as they learn to work in columns and to carry numbers. It's my top recommendation if you need help with this mathematical skill; while it may appear deceptively simple, it is remarkably well designed and can be used independently by children to both reveal and practice the steps of column addition. Problems and settings can be flexibly altered by parents to match their child’s current level of understanding. -- Appsforhomeschooling.com, 2013-02-05 ### ***** "Super!"
