You may want to demonstrate ways to create a ”s” or an “o” using a ruler, because that can be tricky. They can use a ruler to write their name so that they only write straight lines. Once students show proficiency using a protractor, they will love this angle names activity. I’ve found that measuring angles worksheets with an included protractor are easier for students than using their own protractor, that this is a good scaffold for students. You’ll need to give students the opportunity to practice measuring angles with a protractor. Then, I spend a bit of time explicitly teaching students how to use a protractor to measure angles. I like to introduce how to measure angles with the Study Jams slide show on measuring angles. You may even want to record those observations for later reference. ![]() When first giving students a protractor, give them the opportunity to make observations about the protractor. Measuring Angles Worksheet – Using a Protractor Cut out a new, smaller unit and measure a few of the angles. Then, discuss what will happen if the size of the unit decreases. Cut a new, larger unit out and measure a few of the angles. After students have the opportunity to measure, discuss what will happen if the size of the unit increases. If you use the included triangles, the measurements should be similar. If each student creates his/her own wedge the total units needed will vary. Students should use their unit of measure to measure the angles on the Measuring Angles worksheet. Give students an index card and have students draw a narrow angle on the index card and cut it out The wedge that is cut out should be used as a unit of angular measure by counting the number of units that will fit in a given angle. In this lesson students measure angles with a non-standard unit. Hopefully, students will be familiar with the terms acute, right, and obtuse.īefore teaching students how to use a protractor, it is import for students to conceptualize the attribute of the spread of the rays that create the angle. Measuring Anglesīy the time students begin measuring angles, they will have likely learned about types of angles through the geometry in second, third, and possibly fourth grade. In this post, I’ve shared some of my favorite measuring angles worksheets, activities, and lessons. Of course, reading a protractor can be challenging for students, so they will need practice working with a protractor. It’s a math concept that lends itself to hands-on and engaging lessons. On, the exercise tells me.You can really be creative with your measuring angles worksheets and activities. So this is an acuteĪngle right over here. Side opens up or you could say points to 70 degrees. So you want the 0ĭegrees on the side, so the other side is But this isn't too helpful,īecause the angle is now outside. Vertex of my angle at the center of my protractor. And this looks like roughlyĪn 80 degree angle, not quite. So once again, put theĬenter of the protractor at the vertex of our angle. The base of the protractor, at this side of the angle. ![]() So once again, place theĬenter of the protractor at the center, at the Ray, it points to, looks like, pretty close And the other side of theĪngle is within the protractor. Is either rotate the angle or rotate the protractor. Vertex of the angle at the center of the protractor. ![]() Protractor at the center of- or I should say, at the Want to measure an angle, what you want to do Omar Rizwan, who was actuallyĪ high school intern, made this pretty neat module. And I want to giveĬredit to the person who built this protractor, because And it's a pretty coolĪctually measure angles. Of me is the Khan Academy measuring angles exercise.
