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!"

Kelly Tenkely, iPad Curriculum:
"The step by step animation and guidance will help students get the column method of multiplication down in no time. The ability to enter their own numbers means that students can input problems from a math curriculum or textbook and work through the step-by-step process with any problem. Your reluctant math students will love this app, it will act as their own personal tutor sitting with them and encouraging them on!"

The long multiplication method

In arithmetic, long multiplication is the standard procedure suitable for multiplying numbers. The method breaks down a multiplication problem into a series of easier steps.

Carries wrong

When you get to the second row it carries incorrectly. It carries one column to the left and is visually very confusing.

Developer Response ,

Thank you very much for your valuable feedback. The carrying issue that you describe was fixed in version 4.0, and works correctly now.

Upset Teacher

I love this app and used to use it in my fourth grade classroom throughout my multiplication unit as a great opportunity for differentiated, engaging practice with instant feedback! I am very disappointed with the new update though, since it makes the app no longer compatible with my 2nd generation iPods. In the world of education, it is not easy to get the newest technology offered especially when as of 3 years ago my district bought me enough iPods for each of my students. I wish I could still use this app on my class set of iPods, but they can no longer be updated with new software versions. Please allow your apps to continue to work with the older iPod software versions since this was created to help teachers and students in the first place.
