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.

Third graders measure time and length. Through the use of video and technology, they explore key elements of measurement, such as units and conversion between units. They explore alternate units of measurement and apply measurement to...

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...

Fourth graders combine geometry and language arts skills while examining quilt-making. After identifying the geometric shapes contained in quilts, they write stories to encompass the quilt border. Students conclude by creating and...

In this rounding learning exercise, students solve 40 problems in which whole numbers are rounded to the nearest 10. 100 or 1000. Students also round to the nearest dollar.

Students analyze distance and graphing. In this geometry lesson, students work problems on a coordinate grid calculating the distance. They apply the Pythagorean Theorem to their data and answer.

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

In this math worksheet, 6th graders complete multiple choice questions about number sentences, composite numbers, angles, and more. Students complete 30 questions.

Students explore tessellations that are found in nature and everyday objects. They observe the works of M.C. Escher. Students create their own tessellations using pencil and paper.

Students create a matrix of the vertices of a triangle and produce new matrices that dilate, translate, rotate, and reflect the original triangle. After multiplying each matrix by a new scale factor, they graph the new matrix and...

Students explore the concept of polygon properties. In this polygon properties lesson, students draw polygons with different numbers of sides such as pentagons, octagons, hexagons, etc. Students identify different geometric shapes in the...

Fifth graders define the meaning of similar and congruent using concrete objects. They make similar and congruent figures using geoboards. They draw their figures on dot paper, and color their designs.

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.

Recognize parallel and perpendicular lines in geometric figures and pictures. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Use your knowledge about the slopes of parallel and perpendicular lines to solve some problems. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Practice drawing parallel and perpendicular lines, line segments, and ray. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Given points that two lines go through or the graph of each line, classify the lines as parallel, perpendicular, or neither.

Provides examples and a video lesson that illustrates parallel and perpendicular lines.

[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.

[Free Registration/Login may be required to access all resource tools.] Identify intersecting, parallel and perpendicular lines in a plane

The student will verify theorems about angles formed by parallel lines cut by a transversal and apply these relationships to solve problems.

This is an introductory lesson on graphing parallel and perpendicular lines. The students will have a good visual on how these lines relate to each other. This also illustrates how to determine equations in slope-intercept form of a line...
