Defining Angles in the Real-World

Math Vocabulary

Vocabulary building has always been essential to success in math, and teaching angles is no exception. Lessons plans should include learning vocabulary and how the terms and concepts relate to each other.

Angles are the measurement of space between two rays that diverge from a common point or cross a common endpoint.

Teaching angles is a great opportunity for vocabulary building. Students must first understand the concepts of points, rays, lines, vertices, and how they relate to each other. Once they comprehend these concepts, it makes for an easier transition into angles.

Real-World Applications

Teaching angles also allows for an opportunity to learn about real-world applications.

One of the cool things about geometry is that students can physically see what is going on. You can begin your lesson by introducing the concept in a presentation.

For practice, students can work on example problems and vocabulary activities. It also helps to point out real-world examples in your classroom.

Real-world examples can lead to discussion on where they can find examples of points, rays, lines and angles or a quick assessment of do they understand this skill by asking is A is an example of a Term B or Term C. When there is a split decision, let them discuss why they believe in there answer.
