"Depending on your needs, you may not need all of these apps, but each one serves to teach and allow practice in a targeted area. The more ways you play with numbers and manipulate the methods to get to the correct answer, the more you understand how it all works. For anyone having trouble with arithmetic, these apps are an excellent choice for practicing and learning new methods."

"This app is fantastic!!

My third graders loved learning with this app! It has infinite enriching and differentiating possibilities, as the students can select easier or more challenging types of problems."

"We work it out at during homework time and it does wonders, my son actually enjoys doing long multiplication, it is a nice break. "

Long Division:
Pragmatic Mom,

:

"Be still my beating heart! My 5th Grader is learning long division and sometimes working through the problems step by step is confusing to her. So you can imagine how excited I AM with this app, named Long Division, that translates long division into a color coordinated step by step process and has a number key pad so that the student can input their numbers every step of the way. Then, the numbers slide from the problem, into their proper place in the problem. Very visual and memorable!"
