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!"
The Trade-First Method
The trade-first subtraction method is similar to the traditional column subtraction method. The method has two stages. All of the "trading" or "borrowing" is done first. Then the subtractions are solved. This gives the method it's name, "trade-first."
In the Everyday Mathematics curriculum the trade-first method is the focus algorithm for subtraction.
The App is Easy to Use
The numbers are aligned automatically so that you can concentrate on solving the operations for each column.
Borrowing is animated step by step so you can see what happens. Borrowing over several columns is also supported.
After you solve the operation for each column the correct answer will fly to the right place. If the user presses the wrong button the answer will appear above the keyboard but it will not move.
Features:
- Each number can have from 2 to 5 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
- Colors of the interface can be changed
- The speed of the animations can be set
- The lines separating the columns can be hidden
