The Slope Experiment      A 5-page activity that encourages students to "discover" some of the concepts about slope.  Included are teachers notes and solutions.

The Bicycle Production Problem    A 2-page activity that requires students to model mathematically how many bicycles have been produced worldwide from 1950 through 1995.  Included are 4 pages of teachers notes and solutions.

The Pendulum Problem    A 3-page activity that has students model mathematically the relationship between the length of a pendulum and the period of the swing.  The results are very good  --  a complicated formula becomes obvious.

Linking on the TI-83    A 2-page activity that illustrates how to share programs and/or data in lists on TI-83 calculators.

The Sum of a Series Formulae   A 3-page activity that has students investigate the sum of the squares, sum of the cubes, and other patterns, to see if they can model the sum with a formula.  This is an excellent activity with much mathematics and an introduction to "Jim's Maneuver" from Scotland.

The Photography Studio Picture Prices Problem   A 1-page activity that has students determine what relationship, if any, there is between the number of pictures and the cost of the package.  It is a linear relationship and is designed for Algebra I or Algebra II.  Included are 4 pages of teachers notes and solutions.

The 12 Days of Christmas Gift    A perennial holiday treat!  A 2-page activity that has students see if they can come up with two functions that deal with the famous Christmas song:  the total number of gifts sung about each day and the total number of gifts sung after that day.  It is very similar to the Sum of a Series Formulae activity above.  Included is one page of teachers notes and solutions.

TI-83 Golden Gate Bridge Problem      Given a few "points" on the suspension part of the bridge, model the arch it makes with a quadratic equation and answer some application questions.  Similar to the Gateway Arch problem but with a different style and beautiful pictures.  Also included  is some historical information written by the chief engineer of San Francisco's most notable land mark.     COMING SOON TO A COMPUTER NEAR YOU!!!  UNDER CONSTRUCTION
