Lesson Plan

Geometry Vocabulary: Lines

Perpendicular, intersect, parallel! In this lesson, students work in teams to complete a Frayer Model on each of these terms to become masters of geometry vocabulary. Teach this lesson on its own or as support to the lesson What's My Line?

  • Write the word "Geometry" in the middle of a piece of chart paper.
  • Lead students in a think-pair-share about their background knowledge on the term "geometry."
  • Pair up students effectively, give them time to think about anything they know about geometry, and have them share their knowledge with their partner before inviting them to contribute their ideas to the whole-group discussion.
  • Take notes on the information and ideas they provide and create a word map on the chart paper, connecting ideas to the main word.
  • Confirm or correct students' background knowledge and guide them to the discovery that lines are the basis for a lot of geometry. Lines make up shapes, angles, and edges. Explain that there are various types of lines that are important to understand in the world of geometry and today they will learn some of these key types of lines.
