About This Course

Welcome to the Math Medic Algebra 2 course! Here you will find a ready-to-be-taught lesson for every day of the school year, along with expert tips and questioning techniques to help the lesson be successful. Each lesson is designed to be taught in an Experience First, Formalize Later (EFFL) approach, in which students work in small groups on an engaging activity before the teacher formalizes the learning.

Our Algebra 2 course focuses on several function families and develops the graphical, analytical, verbal, and numerical analysis skills needed to flexibly work with these functions, with an emphasis on quadratics. The concept of function transformations is a big theme and woven throughout the course. This course was created using the Common Core State Standards as a guide. The standards taught in each Math Medic Algebra 2 lesson can be found here . The unit overviews and learning targets for the Math Medic Algebra 2 course can be found here .
