Mrs. Rachelle Arechiga

Welcome to Mrs. Arechiga's class!  This is my 20th year teaching mathematics, the last 15 of which have been in NEISD.  I have been at Johnson since its opening, teaching Algebra II GT/PAP, Pre-Calculus Pre-AP, and Calculus AB during that time.  

I grew up in NEISD, attending Stahl, Wood, and Madison.  I then attended Texas A&M University, double-majoring in English and Mathematics.  While I love reading literature and poetry, and I have my students do some writing throughout the year to gain confidence with technical writing, I enjoy the mathematics I teach more.  Upper-level math is fun to me, and I hope to make it enjoyable for my students.


My husband and I have been married for 15 years. I am the proud mom to three boys - James (6th grade), Joshua (3rd grade), and Joel (1 year old). We stay busy with golf, piano, and a toddler.
