Lesson Study Central Elementary School

• Title of the Lesson
• Comparing Polyhedrons
• Goals
• To Identify Solid Figures
• To Name and Count the Faces, Edges, Vertices of
  Prisms and Pyramids
  
• To Learn How Different Views of a Solid Figure
  Compare
  
• To Compare Contrast Polyhedrons and Explain
  their Relationships

Comparing Polyhedrons

• Rationale
• NMSBA Math Scores
• Content Standards
• Benchmarks
• Performance Standards
• Algebra Focus for NMSU LS Project

5
Comparing Polyhedrons

• Question?
• Can students compare polyhedrons, explain the
  relationship and use variables to express an
  equation?

6
Planning and Collaborating

• Discussion
• Connect Geometry and Algebra

Observing

• Public Lesson-February 1, 2007
• Lesson started with large group instruction
• Students applied prior knowledge to the task
  within small groups
  
• Groups presented their findings to the large
  group
  

9
Debriefing

• Short discussion after lesson
• Viewed video of lesson
• Invited fifth grade and middle school educators
  to view the video of the sixth grade lesson.
  
• Debriefed and made recommendations

10
Revising

• Provide more class time to continue the lesson.
• Prepare students to better see the relationship
  between the polyhedrons and the numbers of faces,
  edges, and vertices.
  
• Continue to provide practice until equation is
  developed.
  

11
Comparing Polyhedrons

• If teaching this lesson again we would
• Have a list of questions
• To stimulate thinking in their small groups
• To guide the students into finding relationships
• Give students guidelines
• To work in groups effectively
• To help students communicate their mathematical
  thinking
  
• Anticipate student responses.
