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.
