Description

This app can be used to teach and study the partial sums addition method. The app is easy to use and it has an intuitive interactive interface with customizable colors and other settings. The user can solve random addition problems with small and large numbers. The number of digits in the numbers can be set.

Wired.com:
Esa Helttula’s apps are all fantastic for math learning and practice, and aren’t cluttered with mini-games, incentives, or annoying music.

The Partial Sums Method

The partial sums addition method is a two-step process. In the example 764 + 340, each place value is first added separately from left to right. The resulting addition 1000 + 100 + 4 produces the answer 1104.

In the Everyday Mathematics curriculum the partial sums method is the focus algorithm for addition.

Endorsed By Teachers

R. 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!"

The App Is Easy To Use

The numbers are aligned automatically so that the user can concentrate on solving the operations for each column.

After you solve the operation for each column the correct answer will fly to the right place. If you press the wrong button the answer will appear above the keyboard but it will not move.

Features:

- Custom interfaces for iPhone and iPad
- Each number can have from 2 to 3 digits
- Problems can be custom or random
- There can be 2 or 3 numbers to add
- 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

Not a bad teaching tool - but wicked boring!! Where are the bells and whistles, or score keeping or SOMETHING...?!!
