GPE-B: Use coordinates to prove simple geometric theorems algebraically

Standards:

 

Technology-enhanced investigations:

LearnZillion: Lesson set: Apply the coordinate plane to geometry: Two video lessons: How to prove whether a figure is a rectangle in the coordinate plane and whether a point is on a circle.  Aligns with GPE-B.4.

Math Warehouse: Coordinate Geometry: Using the coordinate plane in proofs: This is an interactive demonstrating how to do coordinate proofs.  Do the proofs (perpendicular segments, trapezoid is not isosceles, and rectangle, parallelogram) and see the answers.  Aligns with GPE-B.4.

National Math and Science Initiative: Lesson: Using Linear Equations to Define Geometric Solids: Use this lesson for geometry within a unit on volume applications.  Students write the equations of lines and graph linear equations that define bounded regions, calculate the areas and perimeters of the regions, revolve the planar regions about horizontal and vertical lines to create solids, and calculate the volumes of the resulting solids; they use technology (virtual manipulatives) to create and revolve planar figures about horizontal and vertical lines and model the conceptual understanding using a real world situation.  Targeted standards include GMD-A.3, GMD-B.4, GPE-B.7 and MG-A.1.  Common Core Math Practice standards 1-7 are also addressed.

Wolfram Demonstrations Project: Download the free Wolfram CDF player to interact with the following manipulatives.  Note: Within the Wolfram Demonstration Project are 2 manipulatives addressing GPE-B.4, 1 manipulative addressing GPE-B.5, and 4 manipulatives addressing GPE-B.7.  Among those:

Multiple Choice:

Khan Academy: Practice questions with videos.

Constructed-response:

AlgebraLab.org: Algebra I: Distance and Midpoint Formulas.  Study aids with examples and practice problems (short answer and T/F).  Given two ordered pairs, determine length of a segment and midpoint.  Given three ordered pairs, determine if the vertices form a right triangle.

Khan Academy: Practice questions with videos.

L. Spector: The Math Page: Skill in Algebra.  Students see worked examples of concepts and following the presentation within each section, students are presented problems in constructed response form.  They would solve using paper-pencil and then by using their mouse to roll over a box, they see the solution to problems presented.

Performance tasks:

Illustrative Mathematics: Geometry:

Mathematics Assessment Project: High School: Geometry: Task 226: Finding Equations of Parallel and Perpendicular Lines

Mathematics Vision Project, Secondary 1 Student Edition:

NCTM's Reasoning and Sense Making Task Library: As the Crow Flies "is designed to help students develop an understanding of the meaning of the [distance] formula. It would be appropriate as an introduction (or review) of the distance formula for students who are familiar with the Pythagorean theorem and coordinate systems."  Learners "compute the distance between two locations in a city with the streets laid out on an evenly spaced square grid." Aligns with GPE-B.4, GPE-B.7, and math practice standards MP-2, MP-4, and MP-7.
