School Improvement in Maryland

Lesson Plans: Lesson plans were written by Maryland mathematics educators and could be used when teaching the concepts.

Goal 2 Geometry, Measurement, And Reasoning

Expectation 2.1 The student will represent and analyze two- and three-dimensional figures using tools and technology when appropriate.

Indicator 2.1.4 The student will construct and/or draw and/or validate properties of geometric figures using appropriate tools and technology.

Lesson Plan

Concurrent Lines in Triangles
Approximate Time: Two to three 50-minute lessons or one to two 90-minute lessons
Objective: The student will investigate points of concurrency in triangles and apply these concepts to real-world situations.

Lesson Plan

Constructions, Sketches, and Drawings
Approximate Time: One 45-minute lesson and a follow-up for 20 minutes in a subsequent lesson.
Objective: For the students to understand the difference between constructions, sketches, and drawings.

Lesson Plan

Different Methods of Construction
Approximate Time: Two to three 50-minute lessons or one to two 90-minute lessons
Objective: For the students to be able to perform geometric constructions using a variety of construction tools, investigate the properties of perpendicular bisectors and angle bisectors, and apply geometric constructions to real-life situations.
