Description
This math app can be used to teach and study the column addition method. The app is easy to use and it has an intuitive interactive interface with customizable colors and other settings.

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
