In need of math vocabulary cards? Use a set of 66 vocabulary cards with topics focused mostly on geometry terms. Each sheet has two cards on it. The top half has the word printed in bold text, while the bottom half has the card with...

Fifth graders work with polygons.

In this figurative language worksheet, students identify the figurative language technique being used in each of the 10 sentences. The sentences are based on Edgar Allan Poe's literary work.

Students observe a demonstration of light refraction. They experiment with disappearing crystals to further study light refraction.

In this literature response learning exercise, students answer 20 short essay questions about Chapter 14 of the book called Holes by Louis Sachar.

In this online interactive math skills worksheet, students solve 10 multiple choice math problems regarding geometry skills. Students may view the correct answers.

In this math worksheet, students look for the words that are related to the math words used in the practice of geometry. They also practice spelling.

Students investigate the law of reflection by using mirrors. In this physics instructional activity, students operate a robot using IR controllers. They explain the path of light as it reflects through a surface.

This fourth-grade geometry lesson plan teaches the definitions for a line, ray, angle, acute angle, right angle, and obtuse angle. We also study how the size of the angle is ONLY determined by how much it has "opened" as compared to the...

Get independent practice identifying points, lines, rays, planes and angles. Each incorrect response gets a text box explanation and another try. Correct responses are confirmed.

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

A list of geometry definitions and a matching activity.

Provides details about the properties of straight lines, types of straight lines, line segments, rays, curved lines, and types of angles.

Students can review basic geometric terms using these self-check, multiple choice questions. Three levels of questions are provided.

Explore lines and angles, and the relationship between the two.

Explains the terms and symbols used to discuss line angles, what an angle is, and the types of angles. Includes short video lesson demonstrating how to use a protractor to measure an angle. [0:57]

In this lesson, learners will identify and draw lines, segments, rays, angles, and points.

In this lesson, students use line segments, angles, and parallel and perpendicular lines in order to create a one point perspective drawing.

[Free Registration/Login Required] In this lesson the teacher will use geometry and spatial sense to distinguish between point, ray, line, line segment and angle. The students will review vocabulary for these terms and then...

The lesson discusses commonly used geometric terms. Definitions and examples of a line segment, ray, and angle are included.

[Free Registration/Login Required] Students use the interactive features of Activstudio to identify and label one and two dimensional characteristics. Students explore rays, lines, end points, line segments, vertices, and angles.

Provides examples and a video lesson that introduce fundamental statements of geometry.

The students will explore angles, rays, line segments, perpendicular lines, parallel lines, and two-dimensional figures through the use of the book Shape Up! Fun With Triangles and Other Polygons by David A. Adler. They will also...
