The Minimax Game
Minimax is a game for two players. Five digits are presented, one at
a time, and used to create a three-digit and a two-digit number.
Each presented digit can be placed in any available position, but
once placed, it cannot be moved.
Before any digits are presented, an operation (addition, subtraction,
multiplication, or division) is chosen, and also a target (minimum or
maximum). The aim for each player is to create the arrangement of
three-digit and two-digit numbers, combined according to the
chosen operation, which produces the better result according to the
chosen target, minimum or maximum.
For example, if addition and minimum are the chosen operation and
target, and the five presented digits are 4, 6, 9, 2, and 5, the
arrangement below of player AAA produces a better result than the
arrangement of player BBB.
Player AAA: 629 + 45 = 674
Player BBB: 954 + 26 = 980
(the lower value is 674, so AAA wins)

The Box Game
Box is a game based on the relative positions of values along a
number line.
A player is presented with nine values, one at a time, each to be
placed into one of nine positions. Only one value can occupy each
position and once placed, a value cannot be moved. The position of
each value must represent its relative size, between the overall
highest and lowest values. If, when a value is presented, there is no
position available to maintain the required order, then the value is
discarded.
The game can be played by two players. Each player completes an
arrangement of the nine presented values. The player discarding
the fewest values (and hence, placing the most values) wins. In the
one-player game, the choices attributed to the second player are
made automatically by the application.
The game can be played using either integer values, decimal
values, or negative values, according to the options selected.
TI-73 / TI-83 Plus SMILE Mathematics App Page 13

The Matching Fractions Game
The Matching Fractions game is based on the concept of
equivalence between fractions.
The aim of the Matching Fractions game is to identify the equivalent
fractions within a displayed set of four fractions. The fractions can
change to new values three times within each round. At the end of
each round your performance is reported as a score based on the
number of equivalent fractions successfully identified in each round.
The game ends after a total of five rounds have been played.
Example
The fractions 2/4 and 3/6 are equivalent fractions because they
both represent the same portions of a whole, which is one-half. The
first diagram below shows a bar divided into four equal parts
(quarters) with two of these parts shaded.
The second diagram shows the same bar divided into six equal
parts (sixths) this time with three of these parts shaded.
TI-73 / TI-83 Plus SMILE Mathematics App Page 17
The fractions 2/4 and 3/6 represent the same shaded portion of the
whole bar. The fractions 4/8, 5/10, 10/20, and 50/100 also
represent the same portion of a whole bar. There are an infinite
number of fractions that also belong to this set. Within this set of
possible fractions, all equivalent to each other, the fraction 1/2 is
the simplest form for any of the fractions in this set.
Viewing Help in Matching Fractions
Text screens provide help with the procedure and game features.
The screens advance when NEXT (s) is pressed and the
BACK (r) option allows earlier text to be reread.
The Help screens explain that:
• There are two levels of challenge, and that level one is the
easiest level.
• At any time, the display shows four sets of fractions.
• Press | or ~ to highlight a displayed fraction, then press Í
to activate the selection.
• RESELECT produces new fraction values for all positions not
already selected. After you press RESELECT three times to see
four sets of fractions, the round ends.
TI-73 / TI-83 Plus SMILE Mathematics App Page 18
• There is an UNDO option which releases the first fraction chosen
so that it can be repositioned, if desired. Undo is not available
once a second fraction has been chosen.
• END GO displays the score for that round.
At the bottom of the final help screen, the DEMO (q) choice
launches a demonstration game sequence with a text commentary.
The demonstration pauses, to allow sufficient viewing time, and
continues when NEXT is pressed. Press QUIT DEMO (o) on the
last screen to move to the SELECT AN OPTION menu.

The Angle Game
The Angle game encourages the development of two important
estimation skills.
• Estimating the size of a given angle.
• Creating an angle of a specified size.
Angles are shown in multiples of 5°. Angles range from 5° to 90° or
from 5° to 360°, depending on the option chosen.
There are three activities within the Angle game:
1. Introduction — an interactive demonstration of how angles are
drawn within the Angle game.
2. Estimation — the player estimates the size of a given angle.
3. Challenge — the player creates an angle of a specified size.
TI-73 / TI-83 Plus SMILE Mathematics App Page 22
Viewing the Introduction
When the 360° game screen is selected (see below), the screen
shows a diagram with multiple angles of 90°, 180°, 270°, and 360°.

Scoring
You are scored on the accuracy of your estimate or drawing,
depending on the mode previously selected. If you are within 5° of
the correct angle, EXCELLENT is displayed. If you are within 10° of
the correct angle, GOOD is displayed.
In Estimation mode, if the estimate is off by more than 10°, you can
TRY AGAIN by pressing GO and inputting another estimate. After
two incorrect tries, the App displays the correct angle.
In Challenge mode, if the drawing is off by more than 10°, the App
shows the correct angle and goes on to the next drawing.
Each EXCELLENT or GOOD score earns a star. At the end of the
game, the device displays the number of EXCELLENT and GOOD
stars earned.
TI-73 / TI-83 Plus SMILE Mathematics App Page 28
The Rhino Game
Rhino is a puzzle game based on coordinates. At its simplest it
reinforces the concept and use of coordinate notation to express
position. After a little basic practice, the Rhino game becomes a
strategy challenge. You have to discover the rhino’s position using
the minimum number of guesses. Information about the actual
position of the rhino is displayed on screen after each turn. The
challenge involves interpreting this information usefully.
This is what the rhino looks like:
Viewing Help
Selecting 1:VIEW HELP from the SELECT AN OPTION menu shows a
series of screens which explain the game situation and tell you how
to play.
At the first screen you have two on-screen options.
• NEXT (s) which moves you on to the next help screen
— or —
• QUIT HELP (o) which starts the game
As you move through the screens, the BACK (r) option allows
you to review an earlier screen. When you reach the last screen,
the DEMO (q) option appears. You can either see the
demonstration or quit the Help screens and play the game.
TI-73 / TI-83 Plus SMILE Mathematics App Page 29
Demonstration
A rhino is at the corner of two New York streets. The objective of
this game is to locate the position of the rhino. After two
coordinates are entered, a helicopter pilot will report the distance of
the rhino from that position.
Tip
This distance is measured in blocks. It is not a direct or diagonal distance, but
the distance a long the streets .
In the demonstration, the coordinates 5 and 6 are entered. A
distance of three blocks is reported and this information is also
shown on the grid. The demonstration then marks, with an “x”, all
possible positions for the rhino, based on that information.
When the demonstration has finished, press any key to play Rhino.
