Showing 1 - 20 of 1,670 resources
Elementary schoolers explore angles, rays, line segments, and more in a fine geometry lesson. The book, Shape Up! Fun with Triangles and Other Polygons, is used extensively. The plan has lots of hands-on activities and terrific teaching ideas to explore geometric shapes, number of sides, parallel lines, perpendicular lines, and angles.

Points, Lines, Segments, and Rays Lesson 15-1
Some of the most important vocabulary in the study of geometry is presented here. In this PowerPoint, learners view the definitions for points, lines, segments, and rays. The definitions and graphics are clear, and kids are also coached on how to "say" the term ("line QS") and how to properly write it using geometric language.

Plotting Pairs of Coordinate Points in all Four Quadrants to Construct Lines
Here is a lesson on coordinates that has pupils view three Cyberchase video clips illustrating the definition of "point" and "line." Along the way, learners will discuss what characters from the videos do, and where problems lie in their reasoning.

New Review Tangent Lines and the Radius of a Circle
Your Geometry learners will collaboratively prove that the tangent line of a circle is perpendicular to the radius of the circle. A deliberately sparse introduction allows for a variety of approaches to find a solution.

Use dance to help learners conceptualize line segments, rays, lines, and planes. They choreograph dances that show dimensional space. Dancers start by pondering space, point, and lines as the teacher draws them in the air. Each movement they make is described in mathematical terminology as it relates to points, segments, rays, planes, and lines.
Lines, Line Segments, Rays, and Angles - Practice 15.1
Is it a line, line segment, ray, or angle? Identifying geometric figures is the focus. In addition to identification, learners recognize right angles or tell if an angle is less than or greater than a right angle. They tell if lines are parallel, intersecting, or perpendicular, and solve word problems.

Lines and Angles with K'NEX
Here is a geometry lessonwhich invites learners to create models using their knowledge of lines, segments, rays, and angles. This lesson reinforces geometric vocabulary and concepts through practical application, it also includes extensions, list of terms, and an assessment.

Lines, Line Segments, Rays and Angles - Reteach 15.1
Upper graders answer four questions where they identify geometric figures as lines, line segments or rays. Next, they answer questions where they identify lines as parallel, intersecting, or perpendicular. Definitions and drawings of each type of figure are provided.
3rd - 5th Math
Lines, Line Segments, Rays and Angles - Homework 15.1
Here is an identifying lines, line segments, rays, and angles worksheet which has learners identify the figures by telling whether figures are right angles, less than a right angle, or greater than a right angle, identifying lines as parallel, intersecting, or perpendicular, and solving a word problem.

Construct and Measure Lines, Segments, Rays, and Angles Using Geometer's Sketchpad
Sixth graders construct points, lines, rays, line segments and angles using Geometer's Sketchpad, label all points and measure each constructed item, print their constructions, and complete question sheet to demonstrate understanding.
Points, Lines, and Rays - Problem Solving 15.1
Here is a set of five word problems in which geometers draw and identify points, lines, segments, rays. They determine if lines are perpendicular or parallel. This is a concise, yet applicable worksheet to help learners grasp the concepts of these figures.

Complementary and Supplementary Angles: Geometry "Nspired"
Learners investigate complementary and supplementary angles. They use dynamic geometry (TI-nspire) software to manipulate rays to identify the conditions necessary to create complementary and supplementary angles. They find the measure of the missing angle given one angle in a pair.

Integers! It All Adds Up!
Young mathematicians add integers using a number line. They create a number line on their Ti-73 calculator. Furthermore, they will add integers on the number line using vectors and addition expressions. Finally, these mathematicians will evaluate real-world examples that compare the values of integers.
