Ms. Noreen Harris

Welcome back to the new school year 2021-2022.  Hi all! I am very much looking forward to meeting you for what we would hope to be a smooth and enriching school year.  

Please click on your class page to get more information on how to proceed. The syllabus is posted and you should browse through it before our first class meeting on Thursday. 


I was born in California and have lived in Arizona for 25+ years.  I graduated from CDO in 2002.  I went to Northern Arizona University in 2008 and graduated with a Bachelor's of Science Degree in Secondary Mathematics Education.  This is my 9th year as a teacher at CDO and I am so excited to continue my career here. 

I make jewelry, and enjoy bicycle riding, hiking and traveling in my spare time when I am not grading. 

Over the summer, I took a road trip to California to visit my grandpa, the Monterey Aquarium, and Sequoia National Park.   

Mathematical Philosophy

I believe students need a strong foundation in mathematics to be successful in STEM (science, technology, engineering, and math) degrees and careers.  Students need a diverse, enriching, and supportive environment to achieve mathematical understanding and mastery.
