A wealth of material to help you plan classroom instruction on complex numbers: several lessons that cover the number i, square roots of negative numbers, and operations involving complex numbers; practice activities, some of which...

This activity allows students to physically create a number line and work on adding and subtracting integers. This lesson can be adapted to include other concepts with real numbers.

This site is a tutorial for students in algebra 2 or for those who need a refresher. The site has explanations, definitions, examples, practice problems and practice tests are found covering topics such as linear equations, graphing,...

Practice using your graphing calculator for real number problems, including the Pythagorean Theorem. 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...

This site from the Northeast Parallel Architectures Center, Syracuse University contains a college level treatment of functions and graphs. Function, element, domain, range, piece-wise functions?? Stuff you know, stuff that's new. Very...

Students learn to estimate the solution set, in real numbers, of a linear inequality using graphical methods on a number line and on a Cartesian (x-y) graph. They also learn how to solve inequalities using tables.

This tutorial for students new to algebra provides explanations, definitions, examples, and practice problems. The practice tests cover topics such as real numbers, fractions, equations, graphing, and exponents.

[Free Registration/Login may be required to access all resource tools.] This lesson covers how to identify the subsets of real numbers and placing a real number into one of these subsets.

This CalculusQuest site is details the power function by looking at the significance of the function, standard notation, the rules of exponentiation, domains and graphs of power functions, and also calculations. This site is a good...

A lesson plan where students will interpret the trigonometric functions in terms of the unit circle, graph a sinusoidal function, and use a sinusoidal function to make interpretations in a modeling context.

This lesson provides basic instruction on the major concepts in algebra. Content includes a focus on fractions, units of conversion, complex numbers, quadratic equations, factorization and roots of polynomials, solving equations, systems...

This is a simple task which has students analyze functions where they assign a father to each student. It addresses the idea that not all functions have real numbers as domain and range values, and the issue of when a function admits an...

The purpose of this task is to apply translations and reflections to the graphs of the functions f(x)=cos x and g(x)=sin x in order to derive some trigonometric identities. There are also rotations 180 degrees about points on the x-axis...

Enter two complex numbers (z and c) as ordered pairs of real numbers, then click a button to iterate step by step. The iterates are graphed in the x-y plane and printed out in table form.

The purpose of this task is to help students make the connection between the graphs of sin t and cos t and the x and y coordinates of points moving around the unit circle. Students have to match coordinates of points on the graph with...

To teach students how to use collect and use real-life data, use this lesson to create, populate and analyze graphs to interpret data related to the growth of plants from seeds. The lesson then asks students to create a story about the...

Rational numbers can sometimes cause problems when they're converted to repeating decimals. That, we can handle. But, what about those irrational numbers that can only be "sort of, like approximated"? How can we expect students to...

This CalculusQuest site provides a basic introduction to exponential functions, covering the laws of exponents and exponential growth and decay. At the bottom of the page are links to exponential equations, exercises, and the...

This site from the Richland Community College provides the detailed lecture notes to a college algebra course, complete with equations and definitions. Content ranges from "functions and their graphs" to "conics and parametric equations."

The Peg + Cat on-air series and online resources provide many opportunities for educators to introduce or reinforce early math concepts. In each 11-minute on-air episode of this animated, math-based series for 3-8 year olds, Peg and Cat...

n this task students use different representations to analyze the relationship between two quantities and to solve a real world problem. The situation presented provides a good opportunity to make connections between the information...
