Lesson Plan for Geometry
Instructor’s Name: Brooke Odle (Fellow)
Teacher’s Name: Maria Sanchez
Course Title: Mathematics (Geometry)
Unit: 4-6
Topic: Equations of Lines
Grade Level: 10
Rationale:
The lecture will cover Equations of Lines (Section 4-6) by reviewing key vocabulary terms
(linear equation, y-intercept, and slope-intercept form) as well as provide the students with a
hands-on application of linear relationships (Vernier activity).
Instructional Goal(s):
The students will understand key vocabulary terms as defined in the textbook as well as
understand what a linear relationship is and how a linear equation describes a linear relationship
between two quantities.
Performance Objective:
The students will volunteer to participate with the Vernier activity and will identify the yintercept of a line as well as the compute the slope of that line.
Lesson Content:
Students will:
 Recall key vocabulary terms from the section
 Determine the y-intercept of a line
 Learn how slope can be computed manually and automatically with Vernier software
 Appreciate the linear relationship between distance and time

Activity to be performed
Review key vocabulary terms and introduce Vernier activity
Vernier activity
Follow-up questions
Note: All times are approximate, and should be revised based upon student progress)
Instructional procedures:
a. Focusing event –Students will be asked to recall key vocabulary terms
b. Bridge/ Connections – To help students understand linear equations, they will explore
the linear relationship between distance and time.
c. Teaching procedures – The lesson will begin with a review of key vocabulary terms and
an introduction of the Vernier activity. After the Vernier activity, several follow-up
questions will be asked to assess understanding of the lesson.
d. Formative check – Students will be asked questions throughout the lesson and will have
to answer follow-up questions at the end of the lesson.
e. Student participation- Students will be asked questions collectively during the lesson.
Students will be asked to participate during the Vernier activity demonstration.
f. Interdisciplinary connections – This activity demonstrates how linear relationships can
be described with a linear equation.
g. Closure- The lesson will end with a few follow-up questions. Students will be asked if
they have any questions about anything presented in the lesson.
Evaluation Procedure:
Follow-up questions will be included at the end of the Powerpoint presentation to assess whether
the students were able to make the connection between the activity and lesson. Students will
also be asked if they have any questions at the end of the lesson as well.
Materials and Aids:
The lesson will require a laptop, Powerpoint, a chalkboard, and the Vernier motion detector,
Logger Pro and software.
