Trace the links between a variety of math concepts in this far-reaching unit. Ideas that seem very different on the outset (like the distance formula and rigid transformations) come together in very natural and logical ways. This...

Overall, this learning exercise contains a good selection of problems that reviews different aspects of linear equations. Learners examine and graph linear equations, absolute value equations, and inequalities in two variables. The three...

In this algebra instructional activity, students examine and graph linear equation, inequalities, and absolute value inequalities in two variables.  The three page instructional activity contains forty-six problems.  Answers...

Having a good working knowledge of math vocabulary is especially important for geometry learners. Here are 119 pages worth of wonderfully constructed definitions, constructions, formulas, properties, theorems, and postulates. This is a...

Eighth graders pick a topic or person to research related to the history of mathematics. They brainstorm and create a concept map, using the multimedia software inspiration, about what they are researching and want to examine. They then...

Tenth graders explore mathematics by participating in hands-on daily activities. Learners identify a list of different shapes and classify them by shape, size, sides and vertices. They utilize tangrams and geometric pieces to gain...

Students observe and solve examples of betweenness, ruler postulate, and segment addition postulate. They complete the Finding the Measure of Segments worksheet using the distance formula.

What did you do over your summer vacation. Young wage earners must compare summer job options, and determine when each job earn the same amount and what that amount be. This be done by creating, graphing, and solving systems of...

Ninth graders develop an understanding of and the applications for linear equations and their graphical displays. They participate in a cooperative learning activity of matching a graphic display with an equation.

For this algebra worksheet, students solve 2 multi-step problems, where they use linear functions to determine the equation of a line.

Students participate in a lesson that reviews the concept of linear functions in connection with preparation for an exam. The teacher reviews problems with the students for scaffolding. Students practice graphing linear functions.

In this Algebra II instructional activity, 11th graders review and apply the basic concepts for solving linear and quadratic equation. The one page instructional activity contains twelve problems. Solutions are not provided. 

In this geometry worksheet, students solve problems that are bimodal. They define properties of circles and triangles. There are 117 questions.

Twenty-five problems cover the topics of slope, parallel lines, perpendicular lines, and transversals in different settings. They are given with each step to the solution cleverly revealed one at a time. You can work each step of the...

Describes and gives good examples relating to the slopes of parallel and perpendicular lines.

Students will investigate the relationship of the algebraic slopes of pairs of lines to the graphical relationship between the lines.

This lesson on slope explains the slope concepts, demonstrates how to use the slope formula, shows how to find slope in horizontal and vertical lines, and how to use slope to find whether the lines through the pairs of points are...

Join Joan the chameleon in an exploration of lines and slope. You'll be drawing lines, calculating slope, using equations and more!

This site from the Northeast Parallel Architectures Center, Syracuse University has a very substantial discussion of math topics slope & line equations. The outline form is quite useful if you need to zero in on one aspect of...

Given points that two lines go through or the graph of each line, classify the lines as parallel, perpendicular, or neither. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or...

Given characteristics of two lines, such as slopes and equations, the student will determine whether the lines are parallel, perpendicular, or neither.

[Free Registration/Login may be required to access all resource tools.] This lesson covers determining if two lines are parallel, perpendicular, or neither and finding the equation of perpendicular lines to a given line.

Students can use TI 73 calculators to explore equations that create parallel and perpendicular lines. Teacher will use the screen capture feature of the Navigator system to display students graphs and equations to discuss observations to...

This activity is for use as a formative assessment tool after the introduction and overview of parallel and perpendicular slopes.
