4.1 Basics of Geometry


Points, Lines and Planes


I.SectionObjectives



  • Understand the undefined termspoint, line and plane.

  • Understand defined terms, includingspace, segment and ray.

  • Identify and apply basic postulates of points, lines and planes.

  • Draw and label terms in a diagram


II.MultipleIntelligences


This section is designed to assist educators in differentiating instruction with the multiple intelligences in mind.



  • Visual Learners- one way to assist visual learners with this lesson is to use the actual objects mentioned in
    the lesson. Where there is a map or a globe mentioned, use an actual map and a globe. This will also assist
    students with special needs in making a connection with the material.

  • Kinesthetic Learners- allow move time so that students can walk around the classroom identifying points, lines
    and planes in their surroundings. Request that students make a list of the things that they find.

  • Interpersonal Learners- have students work in pairs or small groups to discuss their findings from the “walk
    around” activity. This engages students who need to talk about their work to gain a better understanding of a
    concept.


III.SpecialNeeds/Modifications


This section is designed to assist with any modifications or to assist students who face learning challenges.



  • Be sure that all of the vocabulary words are written on a board or overhead as they are presented and discussed.
    Request that students copy this information into a notebook. Reading the terms, hearing them discussed,
    seeing them written again and writing the words themselves assists students in retaining information.

  • Write each postulate on the board as it is discussed.

  • Example 7- Expand this for all learners.


The goal here is to assist students in grasping and learning each term/postulate and its definition. The more students
interact with each term and concept, the more they will remember what has been taught.



  • Draw an example of each vocabulary word. Example, draw three collinear points.

  • Draw an example that illustrates each postulate.

  • Allow students to have an interpersonal connection by discussing their drawings with a peer.


IV.AlternativeAssessment


There are many ways to assess student understanding during a lesson. This section provides a few ideas for that.



  • Walk around and observe students as they work. Are students on task? Are they working diligently? Is the
    conversation appropriate to what is being taught?
