Identify triangles by their angle measures and side lengths by looking at and measuring angle measures and side lengths. Use Cabri Jr. to construct various triangles, then manipulate the construction to create the 6 types of triangles,...

Learners classify triangles and make connections regarding angle measurements and attributes of acute, right, and obtuse triangles. They listen to teacher define and explain triangles. Everyone imagines a place where a broken wing for a...

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.

Students use a protractor to measure angles. They classify angles by type: right angle, acute angles, and obtuse angles. Students build and draw right, acute, and obtuse angles. They discuss how do people in various professions use...

Students identify names of angles. They use a large clock to demonstrate angles using certain times of day. Given a geoboard, students create figures with acute, right, and obtuse 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...

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,...

Elementary schoolers examine the attributes of triangles. In this triangle lesson, learners compare regular triangles and right triangles. They explore vertices and angles and investigate obtuse and acute angles. Pupils draw multiple...

Third graders read the story, Magic Schoolbus Inside the Human Body. Then they form right, acute, and obtuse angles using the joints inside their bodies. They write a brief summary about what they learned about angles as a review the...

Learners identify obtuse and acute angles in comparsion to a right angle. They identify obtuse, acute, and right angles. Pupils use "Shape Measure" to construct obtuse, acute, and right angles. They review line segements to locate right...

Explore with your class the characteristics of acute, obtuse, right, complementary, and supplementary angles. They take digital photographs around the school and identify the angles in the images. Uisng software, they label and...

Young scholars identify and label acute, obtuse, and right angles within a picture. Using Kid Pix software and digital photos, they manipulate, identify, and label the angles and describe the angles to a classmate.

Third graders analyze angles and determine if they are acute, right, or obtuse. In this angles lesson, 3rd graders study the definition and characteristics of each angle. Students then do a worksheet to identify the name of the angle.

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 graders explore obtuse triangles. In this geometry lesson, 4th graders make obtuse triangles with paper and scissors. They determine how to find the center of their triangle.

Students use the Pythagorean theorem to discover the relationships between the lengths of sides of a right triangle. In this right triangles lesson plan, students use their reasoning and mathematical skills.

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

Sixth graders identify and measure right, acute, obtuse, and straight angles. In this geometry lesson, 6th graders review the definition of each angle and are shown examples of each specific angle. Students use toothpicks, gumdrops, and...

Fifth graders create and classify straight, right, acute and obtuse angles. In this clever lesson, 5th graders utilize pretzel sticks to form different types of angles. Best of all, they get to eat them at the end!

Sixth graders investigate the concept of an angle. They classify an angle according to its type. The lesson has students practice with acute, right, and obtuse angles. A unique part is when telling time using clock hands is related to...

Learners 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. 

In this geometry worksheet, students measure various angles. First, they write what type of angle each one is, whether right, acute, or obtuse. Then students estimate the measurement and then write the actual measurement for each angle.

Through the examination of the relationship between the lengths of the sides of a triangles students will learn the classification of triangles (acute, right, or obtuse).

Eighth graders identify and compare acute, right, obtuse, and straight angles. They draw two angles on pieces of construction paper so they can accurately know what it looks like. Students hang the drawings on the wall. They are asked...
