说明
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
- The speed of the animations can be set
