Students investigate the relationship between perpendicular and parallel lines on a coordinate plane. In this geometry lesson, students differentiate lines based on their slopes.

In this worksheet, students identify size and shapes if different circles. They identify the circles as sets of four using a specific pattern.

Sometimes graphing rational functions can feel a little "irrational." Starting with the basics, learners work their way through the pieces of these graphs and finish off with an application question. 

Additive inverse, expression, and irrational numbers are a few terms you'll find when you use a set of 22 flashcards designed to reinforce math vocabulary. The set includes two types of cards; a bold-faced word card, and a corresponding...

Students explore the concept of quadrilaterals. In this quadrilaterals lesson, students use the slope formula, midpoint formula, and distance formula to justify that a given quadrilateral is a parallelogram.

Work on the concept of using division with integer powers. The skills of using exponents and multiplying powers should be in place before attempting this lesson. The lesson provides examples for the teacher to use for direct instruction.

Students explore biological evolution and natural selection and its evolutionary consequences. They also explore how organisms are interdependent on one another.

In this Algebra II worksheet, 11th graders solve equations involving radical equations.  The worksheet provides an explanation and worked examples.  The two page worksheet contains three problems.  Solutions are not...

Young scholars investigate correlations between human body height and other human features. They select ten subjects and record each subject's age and gender and measure for height, wingspan, distance, and size of hands. After measuring,...

Students will solve exponential functions with zero and negative exponents. The problems involve the use of reciprocals and graphs.

Explore opposites and reciprocals through positive and negative numbers and fractions.

Students will "discover" that perpendicular lines have negative reciprocal slopes. [Requires Adobe Reader.]

The lesson teaches students about an important characteristic of lines: their slopes. Slope can be determined either in graphical or algebraic form. Slope can also be described as positive, negative, zero or undefined. Students get an...

The purpose of this task is to lead young scholars through an algebraic approach to a well-known result from classical geometry, namely, that a point X is on the circle of diameter AB whenever angle AXB is a right angle. This consists of...

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,...

A good refresher on multiplication and division of real numbers. Covers finding the reciprocal and performing multiplication with positive and negative numbers and zero.

Learners explore trigonometric identities. Definitions of the Pythagorean, reciprocal, tangent, and negative identities are included.

This site displays formulas and examples, pertaining to slope, for parallel and perpendicular lines.

[Free Registration/Login Required] Students will learn the different forms of an equation of a line and will find the equations of a line in all three forms- point-slope form, slope-intercept form, and the general form (Ax+By=C).

An introduction to solving trigonometric equations by using the reciprocal, negative, Pythagorean, and cofunction identities. Includes several examples and exercises with solutions at the bottom of the page.
