Like other rekenreks or number racks, it allows you to work on big ideas around numeracy, addition and subtraction. You can go from one bead string up to 10 which makes it very versatile as I move between grades and ability levels.
You can also pull up and adjust a "screen" that allows you to shield part of the bead string and is excellent for working on combinations of 10, 20 or 100.

You can also access this amazing app and a great FREE resource on how to use rekenreks in the classroom directly through the MLC's website by clicking here.
Cost: Free for a limited number of games, $0.99 to upgrade to a full version for each type
There is a whole series of these math slide games and I (and my students!!!!) are obsessed with them. The basic premises is that a picture, answer, or equation is shown in the middle of the screen and each player (between 1 and 4 players can play each time) tries to slide the corresponding answer or equation into the middle. The person who does this correctly first has their answer or equation disappear and are one number closer to winning. The first person who gets all their numbers or equations slid into the middle wins.
Here are several different versions of math slide that I currently have on my iPad
Addition and Subtraction
Tens and Ones
Hundreds, Tens and Ones
Multiplication and Division
As you can see... there is something for everyone offered for math slide and I have been using it grades K-6
