Lesson Plan 73
Subject: Geometry
Date: March 3rd, 2008
SOL Objectives: G8a, b, c
Sponge Activities: The activity will include review problems about Trigonometry
parallel lines, special triangles, parallelograms and will include questions from a released
Sol.
Introduction: I will check the homework from last Friday. We will go over the
homework. Then I will ask the students if they have ever seen the Washington
Monument.
Direct Teaching: Today we will discuss trapezoids Chapter 8-6.
Properties of a Trapezoid
A trapezoid is a quadrilateral with exactly one pair of parallel angles.
The parallel sides are called bases. The non-parallel sides are called legs. I will have
students identify the base angles.
The median of a trapezoid is a line segment that connects the midpoints of the two legs.
The median of a trapezoid is parallel to the bases. The median of a trapezoid measures
one half the sum of the measures of the bases.
Guided Practice: We will work on a hand out from page 442, Practice and Apply.
Independent Practice:
The above work will be used for the independent practice as well.
Assessment:
I will use directed questioning to assess understanding.
Closure: I will summarize the lesson by reviewing information that was presented in
class.
