Augustana/Longfellow Number Sense Project (NSP)
 Each software title listed below was developed in collaboration with in-service and pre-service kindergarten teachers at Longfellow Elementary School in Rock Island, IL.  More information about our collaborative design process is available in an article published in the journal Contemporary Issues in Technology and Teacher Education. Each title is available at the Apple App Store for use with the iPad/iPhone/iPod Touch.  Hyperlink access to each app is provided below.  Line ‘em Up, 10 Frame Fill, and Count Sort are free apps.   All other apps are through the App Store and cost \$0.99 each.  A limited number of free access codes are available for these \$0.99 apps.  We are happy to share one code per school site for educators who wish to preview these apps.  Contact us to request a code for a particular title.
 A game designed to promote basic counting and number recognition.  Ah Chute also helps children begin to organize numbers into groups of 5 and recognize “5 families” (e.g. 1 & 4, 2 & 3, 1 & 2 & 2, etc.).
 A very basic game for children just beginning to learn about numbers, Count Sort helps children recognize that counting must be done in a “one-to-one” fashion.  The game also develops early numeral recognition and early recognition of number “families.”
 Designed for children who are ready to start applying their counting and number family recognition skills in the area of basic addition/subtraction, What’s Hiding? provides visual support as children attempt to identify missing addends.
 Intended for more advanced kindergarteners, Pattern Sets requires children to quickly recognize visual representations of numbers without having to count (that is, this app promotes the subitizing skill).  This is an advanced application of number family recognition.  Using the screen shot at right as one example, children will need to “know” that two groups of three is 6.
 Add Sub K-1 supports early development of addition and subtraction concepts by providing children several tools to model the symbolic operations (such as virtual manipulatives, a tally board, etc.).

 The Word Problems program randomly generates basic addition and subtraction “story problems” utilizing the various structures such problems can take (such as “Joining Result Unknown,” “Separating Start Unknown,” etc.).
