How the Teacher Guide is Organized

This guide consists of two sections: Activities

and How to Use the TI-30X ÙS. The Activities

section is a collection of activities for

integrating the TI-30X ÙS into mathematics

instruction. The How To Use the TI-30X ÙS

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 ÙS 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 ÙS key presses.

• A student activity sheet.

How to Use the TI-30X ÚS

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 ÙS, and any pertinent notes about

their functions.

• Transparency masters following the

introductory page provide examples of

practical applications of the key(s) being

discussed. The key(s) being discussed are

circled on the TI-30X ÙS 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.

For example: 

ÙS: A Guide for Teachers iv

Two-Line Display

The first line (entry line) displays an entry of up

to 88 digits (47 digits for the stat and

constant entry lines). Entries begin on the left;

those with more than 11 digits scroll to the

right. Press !and "to scroll the entry line.

Press %!or %"to move the cursor

immediately to the beginning or end of the

entry.

The second line (result line) displays a result of

up to 10 digits, plus a decimal point, negative

sign, x10 indicator, and 2-digit positive or

negative exponent. Results that exceed the

digit limit are displayed in scientific notation.

Display Indicators

Refer to Appendix B for a list of the display

indicators.

Order of Operations

The TI-30X ÙS uses the Equation Operating

System (EOSTM) to evaluate expressions. The

operation priorities are listed on the

transparency master in Chapter 4, Order of

Operations and Parentheses (page 41).

Because operations inside parentheses are

performed first, you can use DEto change

the order of operations and, therefore, change

the result.

2nd Functions

Pressing %displays the 2nd indicator, and

then accesses the function printed above the

next key pressed. For example, %b25 E

<calculates the square root of 25 and

returns the result, 5.

Menus

Certain TI-30X ÙS keys display menus:

z, %h, L, %t, u,

%w, H, I, %k, =

%d, %‚and %.

Press !or "to move the cursor and

underline a menu item. To return to the

previous screen without selecting the item,

press -. To select a menu item:

• Press <while the item is underlined, or

• For menu items followed by an argument

value (for example, nPr), enter the value

while the item is underlined. The item and

the argument value are displayed on the

previous screen.

Previous Entries #

After an expression is evaluated, use #and

$to scroll through previous entries, which are

stored in the TI-30X ÙS history. You cannot

retrieve previous entries while in STAT mode.

Error Messages

Refer to Appendix C for a listing of the error

messages.

Last Answer (

Ans)

The most recently calculated result is stored

to the variable Ans. Ans is retained in memory,

even after the TI-30X ÙS is turned off. To

recall the value of Ans:

• Press %i(Ans displays on the

screen), or

• Press any operation key (T, U, etc.) as

the first part of an entry. Ans and the

operator are both displayed.

-30XÚ

Resetting the TI-30X Ú

Pressing &and -simultaneously or

pressing %and then selecting Y(yes)

resets the calculator.

Resetting the calculator:

• Returns settings to their defaults—

standard notation (floating decimal) and

degree (DEG) mode.

• Clears memory variables, pending

operations, entries in history, statistical

data, constants, and Ans (Last Answer).

Note: The examples on the transparency

masters assume all default settings.

Automatic Power Downé

(APDé

)

If the TI-30X ÙS remains inactive for about

5 minutes, APD turns it off automatically.

Press &after APD. The display, pending

operations, settings, and memory are retained.
