Protractor Teacher Resources

What is a protractor and how does it work? Explore the properties of protractors and how they are used to measure angles. After a quick review of measurement terms and angles, learners are shown why a protractor is necessary for...

Did your students forget to bring their protractors to class again? Using this resourceful copy of four identical protractors, you can easily make a class set or let your students take them home. 

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,...

Measuring angle openings is easy with a protractor, but what if the opening isn't a multiple of ten? Real world examples showcase how protractors can be read precisely. A quick review of the process of estimation starts the lesson. Then,...

Develop a degree of measurement. With the aid of a protractor, the video shows how to measure angles. The segment of a larger playlist on geometry basics points out that it is possible to start at a value other than zero when measuring...

Fourth and fifth graders make a protractor and identify various angle types. In this protractor and angle lesson, learners make their own protractor and use it to measure a variety of angles. They complete worksheets while identifying...

An interactive assignment displays two example angles to teach how to measure them. When you click on the angles, a protractor appears! As practice, learners view a set of angles, estimate the size of each, and then enter the degrees in...

Learners use a protractor to draw, measure, and classify angles. They solve six problems total. Note that the angles all come from a set of three intersecting lines, making this ideal as an enrichment for those who are beyond...

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...

Learn how to measure acute, right, and obtuse angles with a protractor. After reviewing the way the protractor works, fourth graders measure nine angles on their own. For extra practice, have them measure different angles in their...

A nice set of instructions for how to use a protractor is presented. The definitions for a right, acute, obtuse, and straight angle follow. Four angle measures are then given for learners to draw and classify. This would make a nifty pop...

Very simply, geometers draw six angles with the stated angular measure. A protractor is required, so if you assign this as homework, make sure to let learners know that they will need to take a protractor with them. A critical thinking...

Upper elementary learners use a protractor to draw angles having given measures, then classify angles. Houghton Mifflin text is referenced.

Get a quick review on measuring angles with this step-by-step guide using a protractor. Watch the correct way to measure angles and finish with an assessment on correct techniques to measure special angles.

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...

In this geometry worksheet, students measure angles, use a protractor and straightedge and draw angles, labeling degree measures. Houghton Mifflin test is referenced.

Learners use a protractor to solve four word problems, then answer two additional "angle" questions. Houghton Mifflin text is referenced.

Measure how well you know how to measure angles. Learners learn how to measure angles using a protractor. They watch a video that walks through a couple of examples of determining angle measures.

In this TAKS online math quiz worksheet, students take an online quiz focused angle measurement with a protractor. Quiz can be graded online by clicking a link.

Practice those protracting skills while watching the step-by-step guide on the correct way to use this angle measuring tool. The resource follows with assessment questions testing their ability to understand and use the protractor...

Students measure strings. For this trigonometry lesson, students use a protractor and scientific calculators to measure strings hanging from the ceiling. Students use trigonometric ratios.

After watching a brief video on making metric conversions to standard units, pupils complete tables to describe certain items with the appropriate unit of measurement. Then, they convert liters to millimeters, millimeters to centimeters,...

In this angles worksheet, students solve three problems in which a protractor is used to measure large examples of angles. Students write the degrees for each angle. No instructions for the use of the protractor are provided.

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