The 3 types of angles

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...

Three letter-sized mini posters can be displayed in your elementary geometry class when teaching about angles. One provides information about degree measurement and additive properties, and the other two define acute, right, obtuse,...

Take young mathematicians on an exploration of the world of 3-D geometry with this seven-lesson unit. After first defining the terms perimeter, area, and volume and how they apply to the real world, students continue on to learn the...

Four fabulous worksheets are included in this resource, all having to do with the measurement of angles. On the first, anglers will use a protractor to determine the degrees of 10 different angles. An arc is drawn on each. On the second,...

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...

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,...

How do you determine the size of an angle? Pupils learn about degrees and how to measure the size of an angle. The video associates the measurements to types of angles such as acute, obtuse, and right. The additive properties of angle...

Small groups of geometry explorers set out on a scavenger hunt to find angles around campus (or around your classroom if you want them to stay close). Once learners understand the basics of straight, right, obtuse, and acute angles,...

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...

Fourth and fifth graders identify three types of angles, recognize that angles are measured in degrees, measure angles using protractors or angle rulers. They classify angles as a class, classify angles on pattern blocks, and complete a...
