### Mathematics Courses

**Objective:** The OFALycée program brings greater complementarity to students by merging the French program with the American program to provide a comprehensive education with emphasis on reasoning, critical thinking, geometry and programming. This complete math education is a true asset for students in high school, higher education and professional life.

**Duration:**

**4th to 8th Grade:** 1 hour (2×30 minutes) of synchronous lessons per week.

**9th to 11th Grade:** 1 hour (2×30 minutes) of “office hours” meetings per week in groups of max. 6 students with the teacher. Video clips available.

**12th Grade:** Specialty education: 1.5 hours (2×45 minutes) of “office hours” meetings per week in groups of max. 6 students with the teacher. Video clips available.

**Calendar:** September to June

**Our Approach:** At OFALycee, we believe that we can offer one of the most comprehensive math programs in the world, combining two experiences, with different approaches, taught in two different languages.

The mathematics courses offered at OFALycée capitalize on the American experience of our students and the program covered in “Middle School” and “High School” in order to prepare them for the specific skills of the French system.

The American system is particularly effective in preparing students for mastery of algebra by offering a large number of practice exercises. This approach insists above all on technique, and thus abandons reasoning. At OFALycée, we want to improve this approach by emphasizing the meaning, on the basis of each method, convinced that if a student understands the why of a technique, he can better memorize and retain it.

As an organization preparing our students for the French baccalaureate, we strongly support the French mathematics program. The French approach develops reasoning skills in students by emphasizing an analytical approach. The properties of the course are demonstrated and a rigorous and detailed writing of the solutions is expected. However, by emphasizing reasoning, less time is spent on developing algebraic mastery in the student. We believe that these skills are essential for the learning and progression of our students towards mastering complex concepts.

At OFALycée, we have developed a program combining the best that both programs have to offer. Each approach builds complementary skills that will serve the success of our students.

**Workload: Middle School**

The course content covered during the sessions is available on the platform and should be reviewed before each session.

From one session to the next, exercises are given. These exercises require between 10 minutes and 30 minutes of personal work. Several types of exercises are possible:

**On paper:**Geometric constructions, justifications, algebraic calculations, problem solving.**On software:**constructions of dynamic figures on Geogebra, programming on Scratch.

The workload corresponds to approximately 1 hour of personal work per week.

**Workload: High School**

In high school, a large part of the content is given in the form of video clips and documents available on the platform. The meetings allow you to review the content of these videos in order to answer any questions, correct the exercises and focus on specific methods.

From one session to the next, the student may be asked:

- To watch the video clips associated with the session.
- To complete the given exercises. These exercises can require between 30 minutes and 1 hour of personal work.

These exercises are usually to be delivered through the platform. They may require the use of a graphing calculator, dynamic software such as Geogebra or programming in Python (repl.it)

The workload corresponds to approximately 2 hours of personal work per week.

**Approach and Philosophy of the Academic Director:** For Thomas Renault, each lesson is an opportunity to share and pass on his passion for mathematics. Based on the experience of his students and the high standards of the French program, Thomas seeks to develop in his students curiosity, reasoning, rigor and training using an approach that is both challenging and caring.
