Chalkboard Math is a fun, easy-to-use math tutor program that
teaches and enhances elementary math skills in children
between the ages of 5 and 12.  The program can be used by a
single child or by a child and an adult.

The program presents the player with a blank chalkboard area
in which elementary math problems are drawn, answered, and

Progress through a given Chalkboard Math session is measured
via a Scoring Mode option, in which correct answers are
tracked and difficulty levels are automatically adjusted.

The Chalkboard Math package consists of 13 files:

An ASCII text information file, containing program notes and
installation guidelines.  This file can be loaded and viewed
with Windows Notepad or any text editor or word processor that
accepts the ASCII text file format.

The executable program file.

The Windows Help file, used for providing comprehensive
run-time help for Chalkboard Math users.  A registration form
is included in the Help file; both it and any other Help topic
may be easily printed through the Windows Help menu bar
"File/Print Topic" command.

The initialization file, used for storing program
configuration data and the Chalkboard Math high-scores Honor

CM_01.MDF - CM_08.MDF
Music data files for Chalkboard Math's audio hardware support.

This file, containing program information, notes, general
instructions, and an ASCII text format registration form (see
end of file).

Chalkboard Math runs within the Microsoft Windows environment,
and requires the following:

* VGA graphics capability (640x480) or higher.  EGA-equipped
systems do not provide sufficient resolution for the
Chalkboard Math display.

* Microsoft Windows version 3.1 or higher.  This release of
Chalkboard Math cannot be run under previous versions of

Chalkboard Math will detect a Windows-compatible sound card or
other audio hardware, and attempt to make use of that hardware
for its music sound track routines.  Audio hardware is
recommended for Chalkboard Math 1.5, but is not required in
order to run the program.

A Windows-compatible mouse or other pointing device is not
required, but is strongly recommended.

Chalkboard Math runs in 16-color mode, but will run acceptably
on monochrome or black & white VGA systems -- provided the
minimum resolution requirements are met.

Although Chalkboard Math 1.5 can be run from a floppy disk, we
strongly recommend installation to a hard disk.

1. We recommend making a backup copy of your program disk.
Keep the master copy in a safe place and use the backup disk
for program installation.

2. Copy the program files (CBMATH.EXE, CBMATH.HLP, CBMATH.INI)
and the music data files (CM_01 - CM_08) from your master disk
to an appropriate subdirectory on your hard disk (e.g.,

There are no hidden files or "key" files on the program disk,
so the file copying process can be accomplished with the DOS
"COPY" command or, if you prefer, through the Windows File
Manager File/Copy command.

This file, CBMATH.TXT, is not required in order to run
Chalkboard Math.  However, the three program files
(CBMATH.EXE, CBMATH.HLP, and CBMATH.INI) are required, and
must all reside in the same directory in order for Chalkboard
Math to work properly.  The music data files (CM_01 - CM_08)
must also reside in the Chalkboard Math directory; they are
required by Chalkboard Math's MIDI-based music routines.

3. You may use the "Windows Setup" utility to setup a program
item (icon) for Chalkboard Math.  Windows Setup will recognize
the CBMATH.EXE file and assign its icon to a program group for


You may assign a program item icon to Chalkboard Math
manually, through the File/New commands in Program Manager.

Always make sure that the correct path and filename (e.g.,
"C:\CBMATH\CBMATH.EXE") is assigned to the Chalkboard Math
program item.  The "Browse" control in the Program Item dialog
box will make it easy to locate and assign the correct path
and filename.

4. If installed correctly, Chalkboard Math should load from
the Program Manager screen when the program's icon is
double-clicked (or from File Manager when the Chalkboard Math
listing is selected with "Run" or double-clicked).

Chalkboard Math was designed to be fun and easy to use
-- educational software that "feels" like a game to the user,
yet sharpens elementary math skills through eight different
levels of difficulty.

Although Chalkboard Math can and should be used by children to
sharpen math skills on their own, the program is even more
valuable when used by an adult and child together.

Help is available at any time through the Chalkboard Math menu
bar "Help/Contents..." command.  You can directly access any
Help topic through the Contents, or browse from topic to
topic.  Help topics may be printed through the Windows Help
menu bar "File/Print Topic" command.

Chalkboard Math will post a warning or notification message
dialog if it detects an invalid or missing program file during

Depending on the nature of the error, you may still be able to
run Chalkboard Math, but selected program features may be
disabled.  If you are given a warning message, please check to
make sure each of the program files from your master disk have
been successfully copied to the same directory (see

Chalkboard Math's interface opens with the default chalkboard
display and button control panel.

A group of four math mode controls are located along the left
side of the control panel.  These buttons are used to create a
new problem (Addition, Subtraction, etc.) and draw it to the
chalkboard screen.

The mouse can be used for "pressing" any of the four math mode
buttons.  The keyboard numerical keypad "operator" keys (+, -,
*, /) can also be used for selecting the desired problem's
math operation.

Ten numerical button controls (0-9) are provided for entering
the answer to any displayed problem.  These controls are
automatically disabled after an answer has been completely
entered (based on the total number of digits in the answer

The mouse can be used for "pressing" any of the ten numerical
buttons.  The keyboard number keys 0-9 or numeric keypad
number keys 0-9 may also be used for entering answer numbers.

NOTE:  Full use of your keyboard's numeric keypad requires the
keyboard "NumLock" feature to be turned on.

Answers are drawn on-screen from left to right.

A "GO" button control is provided for checking the entered
answer.  The keyboard "G" key can be used for checking the
entered answer.

A "BACK" button control is provided for "erasing" any answer,
allowing the user to start entering a new answer in its place.
The keyboard "B" key can be used for erasing the current
answer and starting over.

Chalkboard Math will create random math problems throughout a
twenty-problem lesson.  Progress through the lesson is
displayed on the yellow "LED" progress meter display along the
underside of the chalkboard graphic.  The meter will fill with
red as each problem is completed.

Comments and score updates are given in the large status
window just under the chalkboard.  If the answers on both the
first and second attempts are incorrect, the answer to the
problem is also provided in the status window.

The complexity of the problems generated by Chalkboard Math
can be manually set via the menu bar "Difficulty" command,
which allows easy selection among eight levels of difficulty.

Chalkboard Math may be run in two different modes, Scoring
Mode or Practice Mode.

In Scoring Mode, Chalkboard Math will compile and track a
user's score, based on the number of correct answers given
throughout a lesson.  A higher score is awarded for correct
answers given on the first attempt.  Proportionally higher
scores are awarded at higher difficulty levels, as well.

If the user's score qualifies, he or she is "inducted" into
the Chalkboard Math Honor Roll, which records the top five
"Math Whizes" and their scores.

In Practice Mode, Chalkboard Math simply provides math
problems and checks for correct answers, but does not track a
running score throughout the twenty problem lesson.  As a
result, you cannot qualify for the Chalkboard Math Honor Roll
in Practice Mode.

NOTE:  Switching modes in the middle of a math session will
clear the score and reset the program.

Although Chalkboard Math's difficulty level can be manually
set via the menu bar "Difficulty" command, the program can
also automatically advance the difficulty level during a
twenty-problem lession.

When Auto-Advance is on, Chalkboard Math will increase the
difficulty level each time five correct answers are entered at
the current level.

Please note the following key features, accessible from the
menu bar:

New Lession
The New Lession command clears the chalkboard area, resets all
scores to zero, and allows the player to restart a Chalkboard
Math lession.

This command is available through the menu bar "File/New
Lession" command.

Honor Roll
The current top five scores, as recorded by Chalkboard Math,
may be viewed by selecting the menu bar "File/Honor Roll..."

Clear Honor Roll
The contents of the Chalkboard Math Honor Roll can be erased
by selecting the menu bar "File/Clear Honor Roll..." command.

Scoring Mode
The Scoring Mode feature can be toggled on and off through the
menu bar "Options/Scoring Mode" command.

Scoring Mode (Enabled)
With Scoring Mode enabled (indicated by a check mark -- the
default), the program provdes the user a total of 20 problems
in a given lession.  The program will keep a running score of
the number of correct answers given.

A higher score is awarded when the problem is correctly
answered on the first attempts.  Higher scores are also
awarded at the higher difficulty levels.

Chalkboard Math maintains a record of the top "Math Whiz"
players and their high scores.  The program will prompt the
player for his or her name if their score ranks in the top
five, and will record their name and score in the Chalkboard
Math Honor Roll, as well as the date on which the score was

Scoring Mode (Disabled)
With Scoring Mode disabled, the program runs in Practice Mode,
and does not track the number of correct answers given or
offer the player the option to automatically advance to the
higher difficulty levels.  However, the player can always
manually select any difficulty level in which to practice.

NOTE:  Regardless of the Scoring Mode setting, only two answer
attempts are allowed per problem.

Difficulty Level Control
The current difficulty level, ranging from 1 to 8, may be
selected from the menu bar "Difficulty" command.  Each of the
eight levels will provide for generation of increasingly
complex math problems.

The Auto-Advance option may be used to automatically increase
the difficulty level when 5 correct answers are recorded at
the current level (see below).

Red stars "thumb-tacked" to the top of the chalkboard frame
represent the current difficulty level.

NOTE:  During start-up, Chalkboard Math always defaults to the
lowest difficulty level (Level 1).

Auto-Advance (Level)
The Auto-Advance option automatically increases the Chalkboard
Math difficulty level when 5 problems have been correctly
answered at the current level.

This command is available through the menu bar
"Options/Auto-Advance" command.

Chalkboard Math may be run with Scoring Mode enabled (turned
on) and Auto-Advance disabled (turned off), allowing the
player to compete for a high score without having the
difficulty levels adjusted during play.

The Auto-Advance option is only available when Scoring Mode is

Help System
Comprehensive run-time help for Chalkboard Math users is
provided through the menu bar "Help/Contents" command.

You may select specific topics to read, or browse from topic
to topic.
