Match the numeral to the number word. A set of numerals in circles is randomly spread out on the screen and a number word is shown. Match the numeral to the number word by tapping on a number in a circle. A correct selection will highlight green. Or, an option to use a “flashcard” with a “whiteboard” to illustrate the number of items the numeral represents is also included. Options include practicing with numbers 1-10; 1-15; 11-20, and 1-20. You can also select to show a number line or ordered set of number tiles as a tool for matching number word with numeral. Tapping the number word will speak the word and tapping a numeral in the number line or tiles will speak the number.

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.
