The class is structured as follows:
We begin each session with warm-up exercises, which are posted on the board. These exercises allow you to actively engage with the material from the moment you enter the class. Afterward, the instructor checks the warm-up exercise and proceeds to present the day's topic. Each concept is explained with illustrative examples, ensuring clarity and understanding. You will have guided and independent practice questions to solidify your mastery of the material.

To enhance your learning experience, we provide challenge activities such as word problems and exercises that are commonly found in SAT/ACT tests. Additionally, we offer extension activities including games, puzzles, and videos, which promote critical thinking and strengthen your analytical skills.

Sometimes, there will be an evaluation to assess your progress. The instructor may also provide recommendations for further study, and optional homework assignments may be offered to reinforce the concepts covered in class.

We value interaction and encourage active participation in our class. You will have the opportunity to interact with the instructor and your peers through discussions, group activities, and sharing different problem-solving approaches. We believe in catering to individual differences and promoting a supportive and inclusive learning environment.

We are committed to your success and aim to provide a comprehensive and enriching learning experience throughout the course.
