About the teacher
|
I teach math at Sandra Day O'Connor. This year I have the priviledge of teaching college Algebra. In my College Algebra classes I have an amazing Co-Teacher named Mrs. Lord. We at O'Connor have pushed into the 21st centry going almost paperless. Both of my courses will have their homework in canvas. All of my notes will be uploaded to canvas for easy access to stay caught up in class or just look over what I have written in class that day. Items to purchase for my class are just the basics. Notebook for notes, pencil for taking notes, and any of the TI-83 or greater graphing calculator. I hope we have a great year together! |

About the teacher
I was born in Santa Clara, California and moved to Seattle, Washington when I was 8. I moved to Phoenix in June 2015.
I went to the University of Washington where I earned my BS in Mathematics with a minor in Chemistry.
After graduating, I attended Seattle Pacific University where I earned my Masters in Teaching Math & Science. While earning my masters, I completed a full year of student teaching at Skyline High School in Sammamish, WA where I taught Algebra 1-2 and Pre-Calculus.
For three years, I worked at The Bear Creek School in Redmond, WA where I taught AP Statistics, Geometry, and Algebra 3-4.
I have worked at Sandra Day O'Connor HS for the past seven years, teaching AP Statistics and Honors Geometry. I have also taught Algebra 3-4 Honors and Pre-Calculus Honors for the Deer Valley Online Learning Program (now Aspire). In addition, I teach Middle & High School Competitive Mathematics with the Johns Hopkins CTY program.

About the teacher
Hello, I am as native to the Valley as they come (born, raised, high school, college and graduate school). I earned my undergraduate degree in journalism and mass communication from ASU and worked for the state for many years. Some time in 2012, while also personal training part time, I decided to return to school to secure the necessary math credits in order to work toward earning my master's degree in secondary education to become a high school math teacher. A few years later, here I am, tremendously excited to start my second career teaching the exceptional students at Sandra Day O'Connor High School. When I'm not at school, I can usually be found out training my run, bike or swim and even occasionally brushing the dust off my guitar or drums.

About the teacher
My name is Amy Hoffman. I am ready to embark on my 21st year of teaching, and 4th year in Geometry.
I grew up in the Chicagoland area as the youngest of three children. I attended Northern Illinois University for my undergraduate degree and my graduate degree at National Louis University. I started teaching for 10 years in Illinois before my husband and I moved our family to Arizona 10 years ago.
Outside of school, I am a wife & mom of three girls. My oldest daughter is pursuing her degree in chemistry and biology and is working toward becoming a research scientist. My second daughter is pursuing her degree in Spanish and Biomedical Sciences and is working toward becoming a doctor. Finally, my youngest daughter is attending Arizona Agribusiness Equine Center (High School) and trains service dogs. I love to share my house with a small zoo of animals including my two boxer pups, a bearded dragon, geckos, fish, and chickens. As you can see, we enjoy our pets, but we also love to play games, go shopping, hiking, bike riding, and just get as much family time as possible.

In my classroom I believe in Love and Logic practices. Everyone can achieve success and should be challenged using the data from each individual's level of ability. I work as a team with parents, students and educators to foster the growth of a strong foundation for future learning. I am excited to begin this year working with you!!
