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
Comparing Polyhedrons Question?
Can students compare polyhedrons, explain the relationship and use variables to express an equation?
Planning and Collaborating
Discussion Connect Geometry
and Algebra
Teaching
Mrs. Armstrong – First Teach
Mrs. Sanchez – Second Teach
Mrs. Armstrong – Public Teach w/Algebra Connection
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
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
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.
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.
