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!"
Z. R. Prowell, Highlands Elementary, Edina, Minnesota, USA:
"In my class I have used them to assist students with seeing the steps to properly completing multiplication operations such as partial products and partial quotients. There are students who see my examples who still need some guidance, and after using your app have said, "Now I get it." The feature of selecting possible solutions in each step helps some of my students who are still building their multiplication facts. They can gain experience in using these new concepts but not be left behind.
Helping student understanding are the animations. They are smooth and really illustrate a step-by-step understanding of how to complete new styles of multiplication.”
The Grid Multiplication Method
The grid multiplication method is a two-step process. In the example 39 x 24 the numbers are first broken up into 30 + 9 and 20 + 4, and written on a grid. Multiplying the row and column headers then solves each cell of the grid. Eventually the partial products 600, 180, 120, and 36 are added together.
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.
Settings:
- Each number can have from 2 to 3 digits.
- Random and custom problems.
- The current operation 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.
