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.
