About

Owlet

Read full description

Owlet: Cube6 is an app that uses two Owlet CubeTower manipulatives. This app builds on the Cube3 app by enabling students to create six-digit numbers by stacking small cubes in the columns of two CubeTowers. Cube6 has three modes. Each corresponds to a different topic in place value: Thousands, Money, and Decimals. For each topic, there are five different activities. - Explore: Students place cubes in the CubeTowers to create numbers that are shown on the tablet. - Make: Students are prompted to make a target number by placing cubes in the CubeTowers. - Build: Students solve number puzzles. For example, students might be asked to build a number between 200,000 and 300,000 using 15 cubes. - Compare: Students create a number in the CubeTowers and then compare it to a number generated by the app. - Round: Students use the CubeTowers to round a number to a specified place.
