From 2000 to 2003, Texas Instruments commissioned programmers from the TI community to create Flash applications ("concept apps") for the TI-73, TI-83+, and 68k graphing calculators. TI wanted to expand the library of educational Flash applications available for the calculators for students and teachers to use in the classroom. Each of the applications was designed to teach students basic concepts, such as common geometry formulas or how to do math calculations step-by-step, and there was an accompanying game or quiz that provided a way for the students to test and reinforce their understanding of the material. All of these applications are available for free on TI's website, and some of them come pre-packaged with the graphing calculators.

Name | Author | Screenshot | Release Date | Description |

Area Formulas | Michael Vincent | November 2001 | Reviews the definition and area formula for the rectangle, square, parallelogram, triangle, trapezoid, and circle. The development of the formulas is explained using animation. | |

Decimal Defender | Jonah Cohen | Spring 2002 | Your mission is to fire the decimal point in the correct place to save your ship. Where should the decimal point be fired when you multiply or divide a number by a power of 10? | |

Guess My Coefficients | Sebastian Theiss | 2002 | You need to guess the coefficients of the line. | |

Logic Ladder | Joel Seligstein | Sometime 2001 | This App contains 2 games — Play Factor, and fill in the prime factorization of a given number. How many tries will you need? Play Classic, and try your hand at ordering 4 to 6 different shapes. Can you determine the correct shapes in the correct order in 9 steps? | |

Math by Hand | Andreas Ess & Clement Vasseur of Icarus Productions | Sometime 2002 | Reinforces how to perform algorithms for addition, subtraction, multiplication, and division. Two learning modes let you enter your own problems and see how they are solved. Game mode presents random problems for you to solve. | |

Number Curiosities | Xavier LaRue | Sometime 2002 | This App illustrates and animates interesting and fun facts about the numbers from 0 through 25. The App was inspired in part by Numbers: Facts, Figures, and Fiction. Traverse a number line to see the factorization, an interesting geometric fact, a number sentence or pattern, and a fun fact about the number. | |

Probability Simulation | Corey Taylor & Rusty Wagner of Assembly Coders Zenith | May 2001 | Simulate random events, such as rolling dice or picking marbles out of a jar, to see how the probability plays out. | |

Rational Number Rampage | Sebastian Theiss | September 2002 | Rational Number Rampage provides a fun way for students to study and learn about the representations of fractions, decimals and percents in three different and challenging games. | |

SMILE Mathematics | Andreas Ess & Clement Vasseur of Icarus Productions | 2000 | SMILE Mathematics contains five SMILE mathematics computer games: MiniMax, Box, Matching Fractions, Angle, and Rhino. These games are designed to help build skills in ordering numbers, choosing equivalent fractions, estimating and drawing angles, and choosing coordinates to find a missing Rhino — reinforcing skills in Number and Operations, Geometry, and Measurement. | |

Solve It! | Matthew Landry | Sometime 2001 | Use your mental math skills to fill in the missing values in the table. Input both a number and an operation to make a true sentence at the Gold Level. | |

US Presidents | Jake Poznanski & Eric Marion | February 2001 | Use your calculator in history or political science to study facts and basic information about the first 43 presidents of the United States. | |

What is My Angle? | Kouri Rosenberg | Sometime 2002 | Practice estimating the size of angles in degree measure. Most angles are shown in real-world settings such as the angle between hands on a clock, TV antennas, and more. | |

World Geography | Fred Coughlin | September 2002 | World Geography will allow students to access latitude, longitude, area, climate information and more! |
