Parents, guardians, and students,

It is my honor and privilege to teach Algebra & Geometry at Lanier this school year. This year, our team is piloting a direct alignment to the Algebra & Geometry components of AP Calculus, which we hope all of our students will take in just a few short years. We are committed to ensuring students receive a meaningful, deep learning experience that prepares them to think critically and enables their success in high school mathematics and beyond. I understand this year will likely look very different from what any of us anticipated. Student achievement is my top priority; so to assist in your child’s academic success, I ask for the following two things:

check the reminder every single class, and;
make sure your student follow the reminder, study the notes, and complete assignments on their own by the due date.

I believe cooperation between teachers, students, and families is necessary to ensure the rigorous, meaningful academic experience we wish to create. We will not be standing beside our students’ sides to enforce our rules, but we ask that you still adhere to the high expectations outlined in the syllabus. That said, attend class promptly, take thorough notes, ensure your work is yours and yours alone (unless otherwise stated), and limit distractions. Algebra & Geometry are crucial components of the SAT, ACT, and more advanced math courses such as calculus.

Our world is becoming increasingly digitized, and I ask that you use this class as an opportunity to learn to study independently, seek answers, and hold yourself accountable. Together, we are confident we will create a fun, enriching environment, even if it is through screens. I look forward to meeting you all and seeing your success.
