Esa Helttula, developer of Long Multiplication and many other educational math apps is introducing a new one: Grid Multiplication.
The Grid Multiplication math app to teach and study the Grid Multiplication Method.
As usual with Esa's math apps, it is clear and very easy to use. It offers an intuitive and interactive interface with customizable colours and other settings.
Math Apps for the iPhone, iPod Touch and iPad from Esa Helttula are easy to use and useful for kids. It takes them step by step in order to understand some of the tricky math concepts. Grid Multiplication is a math app that can be used to teach and learn the grid multiplication method. All these math apps have no timers, no punishments for wrong answers, no gimmicks. They are math apps that offer a clean interface without any distractions. It offers a method that helps and supports the understanding of math concepts.
The Grid Multiplication Method
The grid multiplication method is a form of long multiplication using a Partial Products Algorithm and uses a two-step process:
- Break up one of the numbers and
- then uses the distributive law that a(b+c) = ab + ac
It may sound tricky, but the Grid Multiplication math apps will take your kids step by step with a simple and easy method.
With Grid Multiplication, the numbers are aligned automatically so that the user can concentrate on solving the operations for each column. After kids solve the operation for each partial product the correct answer will fly to the right place. If kids press the wrong button the answer will appear above the keyboard but it will not move.
Math Apps from Esa Helttula can be used to teach and learn and are also suitable for special education students and are used by teachers and schools worldwide.
"Z. R. Prowell, Edina, Minnesota, USA: " There are students who see my examples who still need some guidance, and after using the 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."
R. Zeni, 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. I am so glad to have come across this great educational tool!"
J. Bryson, Kings Mountain, North Carolina, USA: "They seem to think we - as teachers don't know how to do math - but when they see the app solve it the same way we told them - it reinforces what we have been trying to teach them."”
