Whole numbers, fractions or decimals appear at the top of the screen. By touching a number and then sliding down onto the grid students can move and place a set of number cubes. The app has three different modes and the sets of number cubes can represent whole numbers from 1 to 10, fractions from 1/10 to 1 and decimals from 0.1 to 1.0.

The app presents challenges for the students to complete. For example a challenge might be to find two sets of cubes that are equal in length to a given set of cubes. 

A variety of special features make it fun for students to use Number Cubes. Speech is used to describe activities and reward correct answers. Sound effects add to the fun of using the app.

A scoreboard keeps track of students performance and can be kept over time or cleared if the app is used by other students in a classroom situation.
