Practice basic addition and subtraction concepts. Discs are counted, then covered, and some slide out from under the cover. Your job is to tell how many are still hidden under the cover. Work with numbers 1-5 or 1-10. Discs are displayed in a 5-frame or 10-frame format.
The iPad version includes an option to use numbers to 20 in two 10 frames. This option was added at the request of elementary education teacher candidates at Augustana College in Rock Island, IL who were working with kindergarten students. The iPad version also includes an option to count or subtilize the number of discs. That option was added in response to a user request.
Developed as part of the NumberSense Project at Augustana College in Rock Island, IL.

DO NOT WASTE YOUR $$$
Dear fellow educators:
Do not waste $.99 on this! Created in 2012 and still so riddled with bugs that I don't believe anyone has attempted to fix the issues.
With Family Sharing set up, up to six family members can use this app.
