Lessons for the Subjects You’re Teaching
Algebra 1
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.
Algebra 1 sets the foundation for higher-level math by building conceptual understanding around equivalence, solving equations, and the differences between linear, quadratic, and exponential functions. A strong emphasis is placed on analyzing how these functions change and interact in various contexts.
Geometry
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.
Algebra 2
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 Algebra 2, students extend their understanding of functions, equations, and mathematical structures. They explore polynomial, rational, and logarithmic functions while strengthening their ability to reason with and solve linear and quadratic functions. A strong emphasis is placed on problem-solving, building fluency, and making connections between different representations of functions.
Precalculus
Ready-to-use lessons for every day of the school year, complete with expert tips and questioning techniques to support student understanding. Every lesson follows the Experience First, Formalize Later (EFFL) format, an inquiry-based instructional model designed to engage students in discovery before introducing formal definitions and procedures.
In our precalculus lesson plans, students engage in an in-depth study of function families, from polynomial, exponential, and logarithmic functions, to trigonometric and polar functions. They learn to reason analytically, communicate precisely, and apply their understanding to real-world scenarios. The course culminates in an accessible and engaging introduction to the big ideas of Calculus. Each unit includes reviews, quizzes, and tests, all structured into a daily schedule.
AP Precalculus
Ready-to-be-taught lessons for every day of the school year, along with expert tips and questioning techniques to help each lesson be successful. All lessons follow the Experience First, Formalize Later (EFFL) format, an inquiry-based instructional model that encourages students to explore concepts before solidifying their understanding with formal definitions and procedures.
In our AP Precalculus lesson plans, students build a deep understanding of functions, modeling, and rate of change to prepare for higher-level mathematics. The course is aligned with College Board’s AP Precalculus framework and covers polynomial and rational functions, exponential and logarithmic functions, trigonometric and polar functions, and the applications of functions in modeling real-world scenarios. Each unit includes reviews, quizzes, and tests, organized into a structured daily schedule.
Intro Stats
The Math Medic Intro Statistics course is a two-semester course with the intention of giving students experience with the statistical problem-solving process of (1) formulating a statistical investigative question, (2) collecting or considering data, (3) analyzing data, and (4) interpreting results. Compared to AP Statistics, this course is more scaffolded, utilizes a more relaxed pace, and does not cover as much content.
We have ready-to-be-taught lessons for each day of the school year, with perfect alignment to the textbook Statistics and Probability with Applications (4e).
AP Statistics
Our AP Statistics curriculum provides everything you need to guide students through the major concepts of the subject and covers everything in the College Board Course and Exam Description (CED). Each lesson is built using the Experience First, Formalize Later (EFFL) format, which helps students develop statistical reasoning through hands-on exploration before solidifying their understanding with formal instruction.
This curriculum covers data analysis, probability, sampling distributions, and statistical inference. Every unit includes structured lesson plans, practice problems, quizzes, and assessments to prepare students for the AP exam.
AP Calculus
Our AP Calculus curriculum is built for teachers who want to engage students in meaningful, discovery-based learning. Each lesson follows the Experience First, Formalize Later (EFFL) fapproach, which empowers students to explore key concepts before solidifying their understanding through a structured whole-class discussion.
This course is aligned with College Board’s AP Calculus framework and covers limits, derivatives, integrals, and applications of calculus in a logical, student-friendly progression. Each unit includes daily lesson plans, practice problems, quizzes, and assessments to help students be fully prepared for the AP exam.
