Owlet: Cube3 is an app that uses the Owlet CubeTower manipulative. Students create numbers by stacking small cubes in the columns of the CubeTower. Cube3 has five modes.

For each topic, there are five different activities. - Explore: Students place cubes in the CubeTower to create numbers that are shown on the tablet. - Make: Students are prompted to make a target number by placing cubes in the CubeTower. - Build: Students solve number puzzles. For example, students might be asked to build a number between 200 and 300 using 5 cubes. - Compare: Students create a number in the CubeTower and then compare it to a number generated by the app. - Round: Students use the CubeTower to round a number to a specified place.
