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 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 partial product 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.
