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 Partial Differences Subtraction Method
The partial differences subtraction method is a two-step process. In the example 936 - 580, each place value is first subtracted separately from left to right. The partial differences are added and 400 - 50 + 6 produces the answer 356.
In the Everyday Mathematics curriculum the partial differences method is one of the algorithms for subtraction.
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.
Settings:
- Each number can have from 2 to 3 digits
- Problems can be custom or random
- The current operation for each column can be hidden
- The operands of the current operation can be highlighted
- The speed of the animations can be set
