What is the Number Curiosities Application?
This application illustrates and animates interesting and fun facts
about numbers from 0 through 25. The application was inspired,
in part, by the book, Numbers: Facts, Figures, and Fiction
Richard Phillips.
The Number Curiosities application introduces students to four
types of information about numbers from 0-25:
Whether the numbers are prime or composite, and how they
•
are factored
Geometric facts
•
Number sentences
•
Real world facts
•
The Number Curiosities application is a concept application that
TI wants to share with our customers, educators, and students
before the product definition and testing are complete. It is an
alpha software version, and as such, it may contain
imperfections, or the coding may be incomplete.

TI invites your feedback concerning the functionality and
educational value of the Number Curiosities application. Please
