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!"

This works but it doesn't follow the format that I remember at school. It can feel a bit clumsy, because you sometimes need to do two steps in one (when you add the result of the first multiplication to the second multiplication). If the first multiplication gives a double figure, I put both figures in the result column. The result of the second multiplication goes below the first one. Draw a line underneath, and add them up in the same way as a column addition.
