Students broaden their outlook on geometry in their everyday environment. They explore the properties of parallel lines and parallelograms and discover ways to prove the existence of parallel lines and discuss the concept of parallel lines.

Acquaint your class with the concept of parallel lines. Learners watch a PowerPoint presentation about how to write equations of parallel lines. Their understanding of linear equations and slope is taken a step further by the...

Have your class create parallel lines. Students will learn how to identify the different angles created by a parallel line cut by a transversal. Then, they identify and name similar and different angles.

Students construct parallel lines using a protractor and a straightedge. In this geometry lesson, students identify the properties of parallel lines. They use Cabri to graph and observe the lines.

Eighth graders are introduced to the basic concepts of Geometry and their definitions in Euclidean space. They draw and define the following terms: point, line, and line segment. Students also define the terms colliner and...

Students plot pairs of Cartesian coordinates on graph paper and connect points with straightedges. They examine the lines and determine if they are parallel or not by finding the equations of the lines and comparing the slopes. They...

Learners study parallel and perpendicular lines. In this parallel and perpendicular lesson, pupils explore 2-D shapes and determine if the sides are parallel or perpendicular.

Students explore linear equation suing real life scenarios. In this algebra lesson, students find the slope and intercept of a line. They create table of values to plot their graph and draw conclusions.

Fourth graders examine and identify line segments and angles using dot paper to draw them. They look at vertical, horizontal, intersecting, parallel and perpendicular lines, draw right angles and angles that are greater than and less...

Provide your young artists with an opportunity to study the masters and their techniques to become skilled at drawing still life. They discuss and view images from artists like Degas and Michelangelo, practice drawing techniques such as...

Keep your mathematicians engaged using this group linear functions activity. Each of ten groups receives two graphs with both an image and equation, as well as a "who has" phrase to call out the next graph. Scholars stay on their toes as...

Students solve problems dealing with points, lines and planes. In this geometry lesson, students differentiate between parallel lines and planes. They find the intersection of lines and planes.

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

The resource is a good introduction to what makes a proportional relationship between two lines. Discuss the similarities of both lines and the possibility of intersection. Use this opportunity to list other acceptable forms of each...

Tenth graders investigate parallel lines and their special angles cut by a transversal. In this geometry instructional activity, 10th graders identify and find corresponding, alternate interior, and alternate exterior angles formed when...

Students differentiate between parallel and perpendicular lines. In this geometry instructional activity, students make conjectures and apply it to solve real life situations. They collect data and make predictions based on the data.

Pupils identify similar triangles.  In this proportional segments lesson, students identify corresponding sides, set up ratios, and find the length of the missing side of a triangle.  They use the parallel/proportionality...

Students explore intersecting lines. In this intersecting lines lesson, students investigate shapes consisting of parallel, perpendicular, and similar lines. Students investigate these lines in shapes around them.

Learners differentiate between parallel and perpendicular lines. In this algebra instructional activity, students graph linear equations using the slope intercept form. They classify lines based on their slopes.

Students calculate the distance between two points. In this geometry lesson, students define the meaning of the distance between parallel lines. They find the point of intersection of other lines.

Students use writing to show their understanding of parallel writing structures. For this ESL grammar lesson, students view PowerPoints, listen to short lectures and audio presentations. Students categorize phrases, write stories...

Fifth graders complete activities to investigate parallel and perpendicular lines. For this plane geometry lesson, 5th graders watch a movie about parallel and perpendicular lines. Students work in pairs to describe and draw the lines in...

Sixth graders draw parallel and intersecting lines to observe and examine the characteristics of alternate interior angles, vertical angles, corresponding angles, and supplementary angles. Through observation, they discover the...

Students measure angles that are formed by parallel lines and a transversal lines. In this angles lesson plan, students measure and define angles that are made by parallel and transversal lines. They will color code the angles based on...
