How to Teach High School Geometry

Teach For America via edX

This course may be unavailable.


Are you thinking about teaching high school math? Learning how to implement effective teaching strategies is essential to creating a successful environment for both you and your students. In this education and teacher training course, you will learn, from experts at Teach for America, how to teach introductory fundamental geometry concepts and empower students to explore math on their own.

You will have the opportunity to engage in creative teaching practices and learn new ways to imagine and visualize approaches for teaching geometry. You will also learn best practices to better support student learning in a math classroom. If you are preparing for or considering teaching geometry, this course will be ideal for you as you explore effective classroom instructional strategies, operations and better understand the foundational content you will teach in a high school geometry class across diverse student communities.

This course includes a weekly module that covers teaching strategies while also introducing commonly taught high school geometry content including:

  • segment/angle addition
  • basic and parallel/transversal line angle
  • angle relationships
  • perpendicular and parallel linear equations

You can jump between lessons to quickly review geometry content and classroom strategies relevant to your learning interests. This course covers geometry curriculum typically covered in high school classroom and Common Core State Standards (CCSS) alignment is indicated where applicable. No prerequisite knowledge is required, however, basic algebra skills will be useful (as well as a strong desire to make an engaging and inclusive geometry class)!


Week 0: Course Orientation
Introduction to course and foundations of strong mathematics learning.

Week 1/ Module 1: Procedures & Geometric Definitions
Brainstorm and solidify the procedures you want for your classroom as well as learn about the importance of building a strong foundation of geometric definitions and naming schema to utilize throughout the year.

Week 2 / Module 2: Lesson Planning & Segment/Angle Addition
Consider the art of lesson planning with a mathematical mindset. Also, review writing and solving algebraic equations via segment and angle addition concepts.

Week 3 / Module 3 : Lesson Instruction & Introductory Angle Relationships
Consider the importance of brevity and clarity in mathematics instruction. Learn about basic angle relationships such as vertical angles, adjacent angles, straight angles, supplementary/complementary angles, and linear pairs.

Week 4 / 4: Student Practice & Angle Relationships Formed by Parallel Lines
Rethink the ways students can practice mathematics inside the classroom. Also, review alternate interior, alternate exterior, same-side interior, and corresponding angle relationships.

Week 5 / Module 5: Formative Assessment & Reviewing Linear Equations
Consider the necessity of daily, high-quality formative assessment - important for both instructors and students alike. Review forms of linear equations and graphing them on the coordinate plane.

Week 6 / Module 6: CFUs & Writing Parallel/Perpendicular Equations
Brainstorm ways in which you can elicit what students know during the lesson and practice. Learn how to write parallel and perpendicular equations, given certain constraints, in both multiple linear forms.
