Geometric Angles Lesson Plan: What’s the Measure on that Angle?
Submitted by: Joy Hall
In this lesson plan, which is adaptable for grades 3 through 5, students use BrainPOP resources to use and apply vocabulary associated with geometric angles. Students will identify examples of different types of angles and measure them with a protractor.
- Use and apply vocabulary associated with angles
- Identify examples of different types of angles
- Measure angles with a protractor
- Internet and BrainPOP access
- Digital cameras
- Checklist of different types of angles
Preparation:Create a checklist of all the different types of angles students will be exploring in this lesson. If students will only be using the terms right, acute, and obtuse, you can make photocopies of the Graphic Organizer associated with the movie.
You may want to invite parent volunteers to assist students in taking photographs and to lend their digital cameras for the activity.
- Show students the BrainPOP movie on Angles.
- Give individual students or small groups of students digital cameras to use. Then have them search throughout the school for examples of different types of angles. Alternatively, you can send one group of students out a time with a camera while the others stay in the classroom and explore the FYI Features, Experiment, and/or other geometry activities.
- Allow students to create posters, books, or digital presentations with the pictures.
- Give students protractors to measure their angles.
- Follow up with the BrainPOP Quiz on angles.
