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 2.1.2 The student will identify and/or verify properties of geometric figures using the coordinate plane and concepts from algebra.

Lesson Plan

Application of Properties of Quadrilaterals in the Coordinate Plane
Approximate Time: One to two 45-minute lessons depending on the level of student you are working with. This is an excellent way to have students practice BCR's-for all levels of students.
Objective: Students will be able to apply definitions and theorems to verify special quadrilaterals using coordinate geometry.

Lesson Plan

Rectangles and Trapezoids in the Coordinate Plane
Approximate Time: One 45-minute lesson
Objective: Students will be able to find the coordinates of the vertices of special quadrilaterals placed in the coordinate plane.

Lesson Plan

Squares and Parallelograms in the Coordinate Plane
Approximate Time: One 45-minute lesson (Other quadrilaterals may be done as you study them.)
Objective: Students will be able to find the coordinates of the vertices of special quadrilaterals placed in the coordinate plane.

Lesson Plan

The Pythagorean Theorem, the Distance Formula, and Slope
Approximate Time: 45-minute lesson plus 10 minutes in a subsequent lesson.
Objective: For the students to understand the connection between the Pythagorean Theorem, the distance formula, and slope.
