Identifying types of angles meets real-world application in an excellent, hands-on geometry activity. Learners use pipe cleaners and a visual model to independently discover the acute, right, or obtuse angles in their classroom, which...

Use the alphabet as a tool for teaching your class about geometric figures. Break apart capital letters into line segments and arcs. Classify angles as right, acute, or obtuse. Identify parallel and perpendicular lines. An excellent...

Fourth and fifth graders investigate angles and name them according to the criteria for obtuse, acute, and right angles. They examine a human-made yarn pattern on the floor of their classroom and identify angles, vertices, and types of...

Explore angle relationships with a hands-on activity. Young mathematicians begin by drawing parallel lines cut by a transversal and measuring the angle pairs. After establishing the angle pairs, individuals show their understanding by...

It's time to put the angles in place. Using diagrams, the video presents the basic definitions of the four classifications of angles. The segment in an informative playlist on basic geometry also provides informal descriptions of the...

There's more to a quilt than just a pretty pattern—there's geometry! Explore angle classification using an artistic approach to show your class that quilt designs are really just intricate geometric patterns. Here, scholars create a...

Angle ABC is not the same as angle BCA, but it is the same as angle CBA. Help your classes understand naming conventions of angles and, more importantly, the importance of naming angles correctly. Scholars practice the parts of the angle...

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 intersecting lines,...

What a great introduction to the world of angles. See the different types of angles and their corresponding degree measurements. Use the provided assessment to test understanding with a variety of questions. 

Learners sharpen their classification of angles skill with a simple angles worksheet that starts with unlabeled angles and ends with specific angle measures to classify.

Don't be obtuse, this geometry unit is the just the right resource for educating the acute young minds in your class. From classifying and measuring angles, to determining the congruence of shapes, this resource covers a wide range of...

Take a look at these angles: What kind are they? Give mathematicians practice identifying obtuse, acute, and right angles in this categorizing activity. Each type is pictured and explained at the top, and scholars examine nine sample...

Learners analyze the examples of lines and angles. They label 16 pictures of lines or angles with the correct term.

Clever! Supposedly a strong wind blew the letters off of a classroom bulletin board, and now learners connect them according to directions listed. As a result, they end up drawing a line segment, ray, intersecting line, angles, and...

Upper graders solve ten multiple choice problems about angles and measuring angles.

Junior geometers investigate the concepts of angles and turns using straws to perform a hands on activity. This is helpful for kinesthetic learners who have a hard time with mathematics. The lesson includes the dialogue to be used during...

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 exercise, or...

Upper graders examine all angles. In this angle lesson, pupils practice measuring, drawing, and naming angles. They create posters regarding angle vocabulary.

In this geometry worksheet, 4th graders classify and measure 11 angles. They write the type of angle and measurement in degrees on blank lines below each angle.

Students identify, name, and measure angles using playing pool as a motivator in this lesson. They measure, define, and label different angles. They then discuss how their knowledge about angles could be used in a game of pool.

In this angles worksheet, learners analyze a group of 8 angles. There are no directions for use, but students could measure these with a protractor or classify them as acute, right or obtuse.

Middle schoolers cut out triangles and sort them according to angles. In this triangles lesson, students classify triangles according to the angles and sides. They make a study guide to assist in remembering the types of triangles....

Practice angle estimation with a worksheet. First learners estimate three angles within 15 degrees, then they measure and name each angle. A reference website is given for additional activities.

Students identify and create angles. In this angle measurement instructional activity, students use sticks to make models of angles, then measure and name each angle.
