Learners study acute triangles. They measure angles using a protractor, then classify the triangles as either right, obtuse, or acute. Everyone creates a design for a Navajo rug using only acute triangles.

The first of two pages displays various angles as the measure of degrees of a circular arc. An explanation is written, and learners are asked to model each by holding up two pencils as the rays. The second page provides instruction on...

What does a geometric farmer drive? A protractor, of course! A set of assessment worksheets prompts learners to use a protractor as they measure angles, name angles, and identify lines. Use the video as a way to...

Why was the obtuse angle upset? Because it was never right! A valuable resource is loaded with background information on types of angles and lines. Learners review the characteristics of parallel, perpendicular, and...

Students explore angle estimation and measurement. For this angle lesson, students define obtuse, acute, and right angles, and practice measuring angles using a protractor. Students participate in an online angle estimation activity.

Explore types of angles and the characteristics of each. After observing a PowerPoint Presentation, learners tour the school facilities and use a digital camera to capture prescribed angles. Using the digital pictures and written...

Test young mathematicians' knowledge with an assessment aligned to California's fifth grade state standards. The exam covers a multitude of concepts including fractions and decimals, positive and negative numbers, measurement; and...

Young mathematicians learn to see geometry from different angles with this simple printable resource. Providing multiple visual examples of angles, this simple document can be used as an instructional tool, a skills practice...

Help 9th graders identify lines, points, rays, and planes in geometry. They  practice identifying, measuring, and drawing angles of different degrees. This is a fundamental lesson to help students learn the building blocks of geometry.

In this line segments and angles instructional activity, students solve problem solving problems and multiple choice questions about line segments and angles. Students complete 7 pages of problems.

Fifth graders explore the three types of angles. For this math lesson, 5th graders estimate the measure of angles and draw the angles using a protractor.

Rays and angles and Star Wars? It sounds strange, but it's actually a fun game to help fourth graders get good at measuring and identifying angles and rays with a protractor. Each pair of children chooses which Star Wars character they'd...

Young scholars investigate geometric relationship using conjecture about linear pairs and vertical angles. In this geometry lesson, students apply their theorems and previous geometry knowledge to solve for and find angles of...

Students measure angles.  In this angle lesson, students draw angles.  They  use a protractor to measure angles and identify the angle as straight, right, acute, or obtuse. 

Get out those protractors! From any angle, this worksheet will give your mathematicians some good practice. First, they find the measurement of eight angles. Next, they draw eight angles given the measurement. 

Get out those protractors! Geometers measure interior and exterior angles of 10 polygons, including a 24-gon. They also calculate the interior angle sum of the polygons. 

Young scholars review what they comprehend about angles. They name the differnt types of angles and define them. Students use their protractors to answer questions, the teacher walks around to look at the positioning of the...

Sixth graders investigate different types of angles. In this geometry lesson, 6th graders use a protractor to identify acute, obtuse, and straight angles.

Fifth graders investigate possible solutions to a word problem. They explore properties of polygons and right angles. Students demonstrate proper angle measurement. Students discover patterns.

Students measure angles using a protractor. In this geometry instructional activity, students solve for the missing angles using equations set to the theorem of triangles. They measure missing angles through construction and identify...

Students investigate angles through construction. In this geometry lesson plan, students use a protractor to identify the measurement of an angle. They identify angles cut by a transversal and two parallel lines.

Sixth graders investigate triangles and the inequality theorem. They will collaborate in groups to determine the length of a longest side of a triangle. Then relate the size of the triangle to its angles using protractors, yard sticks,...

Learners practice estiminating and measuring angles. After watching a short video, they identify angles in objects in the classroom and their homes. In groups, they participate in activities in which they are given a scenerio and are...

Learners measure and label specified angles. In this angles lesson, students use a protractor to find angles that are acute, obtuse, and reflexive. Learners then label each angle and match the angles the correct definition. This lesson...
