Fifth graders use the SMART Board to demonstrate how to use a protractor to measure acute, obtuse, and right angles. In this protractor lesson plan, 5th graders also complete an angles worksheet.

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...

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...

Students explore angle relationships and measure angles with a protractor by hand and online. They explore various websites and complete online activities and complete a worksheet.

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 cardboard cutout with movable handles to create a homemade protractor. They move the handles to create different angles. They identify the angles and discuss their differences.

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. 

Tenth graders construct geometric figures using compasses and protractors.

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.

Pupils practice drawing geometric figures. In this geometry lesson plan, learners complete an activity that requires them to draw angles and shapes to the nearest degree.

In this measuring angles worksheet, young scholars use protractors to measure 9 angles and classify them as obtuse, straight, acute or right angles.

Sixth graders interpret, create, and display data in a circle graph. In this circle graph lesson plan, 6th graders use a compass, protractors, pizza boxes, and more to create a circle graph and analyze the data they put into it.

Students examine how astronomers use parallax to determine the distances of stars in the Sun's neighborhood. They construct a pinhole protractor, and measure angles and calculate distances.

Students create angles using mirrors. In this angle reflection instructional activity, students draw angles, then use mirrors to create angles using reflections and measure the new angles.

Is that drawn to scale? Capture the artistry of geometry using the ratio method to create dilations. Mathematicians use a center and ratio to create a scaled drawing. They then use a ruler and protractor to verify measurements. 

Demonstrate how the Skywatch website works, locating your city via The International Space Station. Have cooperative groups use string and a protractor to identify an azimuth. When each groups' height has been marked, you will have a...
