Explore the concept of projectile distance through determining the angle that will provide the maximum distance of a launched projectile.  Students launch baseballs on a football field and video tape the path of the ball.

Pupils write systems of equations in an augmented matrix and enter it into their calculator. They use the reduced row echelon function on the calculator to solve the system of equations.

Pupils investigate linear, quadratic, and exponential regressions. They plot sets of data points, determine the regression equation that best fits the data and lastly investigate the coefficient of determination.

Investigate differential equations with your class. They use the TI-89 to explore differential equations analytically, graphically, and numerically as the examine the relationships between each of the three approaches.

In this Algebra II lesson, high schoolers explore the connection between the factored form of a quadratics and the zero of a function. Students use a graphing calculator to verify factoring numerically and graphically.

Learners investigate relations in this algebra lesson. They graph the set of ordered pairs that determine a relation. Using a TI-83 Plus, your learners will enter the coordinates in a list, create a scatter plot, and manipulate the...

Have the class learn about and make conjectures about a line intersecting a cubic.  In this making conjectures about a line intersecting a cubic lesson, students draw lines that intersect a cubic at three different points. ...

Learners investigate concept of matrices through iteration in this probability lesson. They investigate probability by creating a lesson based on a famous painting. This assignment contains extensions to the...

Students examine complex numbers. In this Algebra II lesson plan, students investigate two programs that involve complex numbers: the MANDELER Program and SYNDIV program.

High schoolers conduct chemical experiments. In this chemistry lesson, they investigate reactions using the CBL system. Learners will graph and analyze their data using a TI.

Learners find common ratios of geometric sequences on a spreadsheet. Using this data, they create scatter plots of the sequences to determine how each curve is related to the value of the common ratio. They will consider whether series...

High schoolers explore the problem of maximizing the volume of a box by making a physical model and observing how changes in the orientation of the paper changes the volume. They use the symbolic capacity of their calculators and...

With the assistance of their Ti-84/Ti-83 Plus calculators, students develop a foundation for the limiting process as well as estimate limits from graphs and tables of values. They view how a function behaves as the input approaches a...
