What is the Logic Ladder Application?
The Logic Ladder application contains two activities:
In Factor, you determine the prime factorization of numbers
•
by selecting the correct bases and exponents.
In Classic, you order four to six different shapes, determining
•
the correct shapes in the correct order in less than nine
steps. Clues give you an idea of how close you are to the
correct sequence.
The Logic Ladder 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 Logic Ladder application. Please send
your comments and questions to concept@list.ti.com.
