Protractor Teacher Resources

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. 

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...

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.

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.

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.

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.

Get out those protractors! From any angle, this worksheet will give your mathematicians some good practice. First, they find the measurement of eight angles. Next, they draw eight angles given the measurement. 

For measuring angles, use a protractor. Using this tool accurately is a valuable skill for your physics stars. This brief video clip can be used to teach your class how to measure correctly.

Learners 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 learning exercise, students measure angles, use a protractor and straightedge and draw angles, labeling degree measures. Houghton Mifflin test is referenced.

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.

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