A very basic set of activities for children just beginning to learn about numbers. Using numbers up to 32, Count Sort helps children recognize that counting must be done in a “one-to-one” fashion. Options exist to limit the counting target to 10, 15, 20, 25, and 32 chips. The activities also develop early numeral recognition and early recognition of number “families.” The iPad version includes an option to display the chips in 10 Frames. Developed as part of the Number Sense Project at Augustana College in Rock Island, IL.
