Practice using your graphing calculator for Geometry problems. If you get stumped or if you would like to check your work, then select the View Solution button, which is located directly under each problem.

In this activity, students extend their understanding of theoretical probability and patterns. They use number cubes, to build awareness that a fraction and its decimal and percent representation on the calculator are "close," but not...

This activity will show a function with rectangle areas on the graphing calculator.

A concise graphing calculator lesson on calculating average. Detailed examples, demonstrations of calculator functions, and practice problems included. Acrobat Reader required.

Estimate sums and differences for positive proper fractions, n/d (numerator/denominator). Use rounding to estimate answers when adding or subtracting proper fractions.

Calculate basic summary statistics for a sample or population data set including minimum, maximum, range, sum, count, mean, median, mode, standard deviation and variance.

Calculate the percentage weight of two or three numbers that make up a total sum of the sample set, as in vote percentage calculations for an election.

Variance is a measure of dispersion of data points from the mean. Low variance indicates that data points are generally similar and do not vary widely from the mean. High variance indicates that data values have greater variability and...

Calculate mean, median, mode along with the minimum, maximum, range, count, and sum for a set of data.

Students will learn how to program the TI 83/84 Plus graphing calculator to approximate the area under a curve using Left,Right,Midpoint Riemann Sums, and Trapezoid Rule, and Simpson's Rule.
