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.

Learners use their graphing calculators to view graphs of equations. They tell if each equations is or is not a function and are shown pre-set graphs on their graphing calculators. They use the Quick Poll feature to indicate if the graph...

Statisticians take things to new heights using a set of height measurements. Students use TI-82 or TI-83 calculators to determine extreme values and the median for the data. They also construct a box-and-whisker plot to summarize the...

Pupils explore the concept of collecting data as they collect data on their graphing calculator about time, temperature, and light. Learners plot the data and create histograms and box and whisker plots to analyze the data.

Students explore multi-step equations. In this pre-algebra/algebra I activity, students use the TI-nspire computer algebra system to check the steps they used to solve multi-step equations and equations with variables on both sides.

Pupils explore the concept of fractions and decimals as they try to find as many fractions as possible that are equivalent to .25. Learners use their calculator to take screen shots and send them to the teacher via Ti-Navigator. They...

Leanrers observe models of fractions and use a calculator to represent numbers as decimals, fractions, and percents. They participate in calculator activities to view different representations of the same number.

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...

High schoolers explore an application of definite integrals. They graph three functions that go through the same three points. Learners use the symbolic capacity of their calculators to find the shortest path through the three points and...

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.

Learners evaluate the relationship between rainfall and runoff of a small island for one year. In this rainfall vs. runoff lesson plan, students analyze the relationship between the rainfall and the runoff on Barro Colorado Island over a...

Pupils explore the concept of pyramids. They determine if two sides of a pyramid are perpendicular using a graphing calculator, then discuss parallel and perpendicular lines and how to determine if two lines are parallel or...

Learn how to evaluate the derivatives of polynomials.  Mathematicians find the derivative of a quadratic function and determine the value at a given value.  Students compare the slope of the secant line through two points with...

High schoolers study the concept of mean values using a data plot. Learners enter the given data in the activity to create their data table. They use the data table to calculate the mean of the snowfall percentage provided in the...

Young scholars construct inscribed angles using Cabri Jr. They draw a circle on their graphing calculator, then construct an inscribed angle and measure its angle measures. Learners drag the inscribed angle around the circle. They make...
