High schoolers log their computer usage hours. They determine the mean, median, mode and standard deviation of the collected data. They make a frequency histogram of the grouped data, both on graph paper, and on the TI 83+ graphing...

Have your class investigate Piecewise functions by matching a position versus time graph to the function that describe the walk.

Students compare two object as they find the distance between them. In this geometry instructional activity, students create an equation describing the distance of time as a function. They use the navigator to observe the distance.

Pupils solve equations by elimination and use the TI to graph the lines and find the point of intersection.

Learners engage in a lesson that is about finding the vertex of a parabola while using symmetry. They use the symmetry to find out where the two lines meet. The line is displayed with the help of a graphing calculator. The lesson...

Pupils engage in the practice of creating a scatter plot with the data obtained from measuring different resting heart rates. The data is used to create the table that is translated into a graph. The lesson gives instructions for the use...

Students solve equations by taking the derivative. In this calculus instructional activity, students solve parametric equations implicitly. They use the TI-calculator to graph their equations.

High schoolers collect and graph data. In this statistics lesson, students analyze their plotted data using a scatter plot. They identify lines as having positive, negative or no correlation.

Learners graph system of linear inequalities in this lesson. Your class will use the Inequality Graphing App to enter linear programming functions into the calculator that can be stored for later use. They then determine the maximum for...

Use measures of variance to compare and analyze data sets. Pupils match histograms of data sets to their respective statistical measures. They then use calculated statistics to further analyze groups of data and use the results to make...

Students graph coordinate points to create a picture of Snoopy. In this coordinate point lesson, students read a book and learn about Rene Descartes' invention, the coordinate grid.  Students graph a surprise picture on...

Learners practice decoding messages given the key. They continue to practice solving messages without a key. They must determine the best way to view the message. They examine secret messages during World War II.

Students explore the concept of exponential growth.  In this exponential growth lesson, students manipulate power models with base 2.  Students discuss what would happen if you doubled a penny over the course of 20 days. ...

Alegebra amateurs identify the slope and the y-intercept given a linear equation in slope-intercept form by correctly completing some in class problems. They write the linear equation in slope-intercept form that corresponds to the given...

Question: What do rectangles and bathtub volume have in common? Answer: Linear equations. Learn how to identify situations that have constant rates by examining two different situations, one proportional and one not proportional.

Students explore proportional reasoning.  For this middle school mathematics lesson students investigate scale drawings as they create a proportional representation for the carvings on Mt. Rushmore.

Statisticians analyze a data set of student IQs by finding measures of central tendency and dispersion such as mean, median, mode, and quartiles. They practice using a graphing calculator to find the values and analyze box plots and...

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...

Students explore quadratic functions. In this function family worksheet, students examine the quadratic function and the family of functions. They identify the affects of the shape of the parabola and its position on the coordinate...

Pupils graph polynomial functions and analyze the graphs. They identify the inverse of the functions and find the domain and range. Learners will then label the functions as one to one and use the horizontal and vertical line test to...

What if you were paid to attend class? What kind of payment schedule would you choose? Learn how exponential functions will eventually exceed linear functions by comparing two different payment schedules for attending class.

Recycle, reuse, and rearrange! Young scholars learn to rearrange formulas to highlight a variable of interest. They then use their new formulas to make calculations.

Using a TI-Nspire calculator, learners will work to better understand function notation and input/output functions. They write equations with a function symbols, identify what makes an equation a function, and graph lines in order to...
