About the Teacher Guide
How the Teacher Guide is Organized
This guide consists of two sections: Activities
and How to Use the TI-30X
Ù
S. The Activities
section is a collection of activities for
integrating the TI-30X
Ù
S into mathematics
instruction. The How To Use the TI-30X
Ù
S
section is designed to help you teach students
how to use the calculator.
Activities
The activities are designed to be teacher-
directed. They are intended to help develop
mathematical concepts while incorporating the
TI-30X
Ù
S as a teaching tool. Each activity is
self-contained and includes the following:
•
An overview of the mathematical purpose
of the activity.
•
The mathematical concepts being
developed.
•
The materials needed to perform the
activity.
•
The detailed procedure, including step-by-
step TI-30X
Ù
S key presses.
•
A student activity sheet.
How to Use the TI-30X
Ú
S
This section contains examples on
transparency masters. Chapters are numbered
and include the following.
•
An introductory page describing the
calculator keys presented in the example,
the location of those keys on the
TI-30X
Ù
S, and any pertinent notes about
their functions.
•
Transparency masters following the
introductory page and providing examples
of practical applications of the key(s) being
discussed. The key(s) being discussed are
circled on the TI-30X
Ù
S keyboard.
Things to Keep in Mind
•
While many of the examples on the
transparency masters may be used to
develop mathematical concepts, they were
not designed specifically for that purpose.
•
For maximum flexibility, each example and
activity is independent of the others.
Select the transparency master
appropriate for the key you are teaching, or
select the activity appropriate for the
mathematical concept you are teaching.
•
If an example does not seem appropriate
for your curriculum or grade level, use it to
teach the function of a key (or keys), and
then provide relevant examples of your own.
•
To ensure that everyone starts at the
same point, have students reset the
calculator by pressing
&
and
-
simultaneously or by pressing
%
and then selecting Y (yes).
Conventions Used in the Teacher Guide
•
In the text, brackets [ ] around a key’s
symbol/name indicate that the key is a
second, or alternate, function.
For example:
Z
•
On the transparency masters, second
functions are shown just as they appear on
the keyboard.
