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?
