Resources to help you plan classroom instruction on absolute value inequalities: a lesson with several examples and step-by-step solutions; a six-question quiz with answers; and a teacher resource with guidelines for setting up and...

This section explores the concept of sampling variability in the sample proportion. It will address the effect on the mean and standard deviation of a sample distribution as the sampling size changes.

This section introduces the idea of the tails of a distribution, and provides exercises to help you become proficient in determining the type of test associated with various situations.

Learn to analyze examples of claims presented in the media that involve estimating a population proportion and population mean.

This section introduces the concept of Margin of Error. Explore how results from surveys are most accurate within a range of values, and use this concept to make inferences about the preferences of a full population, given data from a...

This lesson continues exploring the process for modeling real world scenarios by writing and solving exponential and logarithmic functions. It also covers how to create and interpret graphs of such functions.

Activities in this lesson explore how to identify the coordinates where special right triangles intersect with the unit circle in all four quadrants, use both degrees and radians to identify angles, and explore angles of different sizes...

Use this tutorial to revisit right triangle trigonometry.

Explore what the standard deviation is as it relates to the graph of a normal distribution curve.

This section explores the graphs of sine and cosine functions. It investigates how these graphs are related to coordinates for different angles in a unit circle.

This section introduces the transcendental number e which is a special number that is considered a natural base. In addition to exploring how to simplify and solve equations with e, this section also investigates how it can be used to...

This section explores right triangles with three lengths that are considered Pythagorean Triples, and also investigates how some right triangles can have lengths that are not Pythagorean Triples.

This section will explore how to determine the domain and range of a function as well as to find the restrictions for the domain and range.

This section explores the process for finding values for x that make polynomial equality true when written in terms of x and set equal to zero.

Given the sine (or cosine) of an angle, find its cosine (or sine) using the Pythagorean identity. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Given a verbal description of the rate of change of a real world situation, find the exponential function that models it. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive...

Pre-algebra and algebra lessons, from negative numbers through pre-calculus. Grouped by level of study. Lessons are practical in nature informal in tone, and contain many worked examples and warnings about problem areas and probable...
