How to Use a Protractor to Measure Angles
Once your students can name and classify acute, obtuse, right, straight, reflex and revolution angles, it is time for them to learn how to accurately measure these angles using a protractor.
A protractor is a mathematical instrument used for measuring the size of angles in degrees. Protractors come in two sizes: 180 degrees (a hemisphere shape) or 360 degrees ( a circle shape).
This set of two posters has been designed to familarise your students with using a 180-degree protractor to measure acute, right, obtuse and straight angles, and using a 360-degree protractor to measure reflex angles.
Each process is explained using labelled diagrams and a series of clear steps that are easy for your students to follow.
Multiple Applications for These Measuring Angles Posters
These versatile posters can be used in various ways to enhance your students’ learning of measuring angles using a protractor. Here are some suggestions.
- Print the posters on A3 paper and display them in your classroom as a reminder of how to correctly use a 180-degree and a 360-degree protractor.
- Print the posters 2-to-a-page and provide the students with a smaller copy to paste into their workbooks for future reference.
- Project the posters onto your whiteboard, then black out some of the words. See if your students can correctly identify the missing words in the process.
