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.
