Mrs. Rachael Kowalski


Hello students and families!  We have an interesting school year ahead of us but I am ready to be adaptable, organized and communicative. I feel confident that I will provide a wonderful math education and overall positive educational experience for your child and I look forward to meeting my new students virtually or in person!

I am in my 17th year of teaching math, 15th at Plano Senior High.  I've taught Math Models, Algebra II, Precalculus and several years of Honors Precalculus.  I love teaching this course and enjoy working with your children! I believe everyone can learn and I enjoy the new arrays of personalities I get to work with each year. 

A little about me - I grew up in a small town in Kentucky and later attended Southern Methodist University, graduating with degrees in both Computer Science and Mathematics.  I earned my teaching certificate soon after graduating.  

I am married, have 3 young boys and a sweet Aussie/Brittany mix dog.  I enjoy music and play several instruments in my spare time. I absolutely love the outdoors and nature and thoroughly enjoy travel.
