Math Medic Geometry Units
Ready-to-be-taught lessons for every day of the school year, along with expert tips and questioning techniques to help the lesson be successful. All lessons are in the Experience First, Formalize Later (EFFL) format, an inquiry-based instructional model.
In our geometry lesson plans, students develop reasoning, justification, and proof skills through an in-depth study of shapes and their properties, rigid transformations and congruence, and the relationship between similarity and right triangle trigonometry. In addition, we include an extended unit on statistics, data analysis, and probability. Each unit has reviews, quizzes, and tests, organized into a daily schedule.

Complete Your Curriculum With Assessments
While lesson plans are always free with a Math Medic account, our Assessment Platform provides ready-made and editable homework, quizzes, and tests that align perfectly with our lesson plans. Our Assessment Platform allows teachers the flexibility of adapting our assessments to meet their own needs, delivering assignments digitally or on paper and even sharing them among teaching staff – right from the platform.

Why Choose Math Medic?
Comprehensive Curriculum
Math Medic is an all-in-one package for your classroom. We provide a day-by-day schedule with all the supplemental materials you need. The lessons are free, while homework, quizzes, and tests are available as add-on services.
Discovery-Based Learning
We use a discovery- or inquiry-based lesson model that uses activities to enable students to guide the lessons. Teachers don’t lecture but respond to the students.
By Teachers, For Teachers.
Math Medic was created by high school math teachers based on years of experience in the classroom. We’re not a publishing company, we’re your colleagues—an extension of your math department.

None! The Math Medic curriculum is not aligned to a textbook. We created the sequence of topics based on the Common Core State Standards and our experiences of what worked well with our own students. For homework, quizzes, and tests, we use the Math Medic Assessment Platform to supplement the lessons.
