    Teacher Message:
    Dear students and families,
    It is a privilege to be a part of your child's math education!  I look forward to learning about your student's strengths, their interests, and what and who inspires them to attain an excellent education.  In my classroom, students will have a place of belonging that embraces every part of their identity and a learning community in which every student has a responsibility to each other to learn and to coach.  Math is one of the most important subjects because it opens the most academic opportunities in college.  Because of this, I will teach math with a sense of urgency and a sincere feeling of love for your student's future aspirations. I have high expectations because I care about how your student will perform in college.  If you are interested in learning more about the courses I teach, please review the algebra syllabushonors pre-calculus syllabus, and AP calculus syllabus.
    Looking forward to working with you,
    Ms. Barrios
    I graduated with my Bachelor's degree in sociology and mathematics from the University of San Diego.  While there, I was a member of various academic organizations and community based organizations.  I truly enjoyed my time while at college and learned a tremendous amount of who I am as an indvidual.
    I moved to St. Louis when I graduated college to teach math at Gateway STEM High School.  In 2012, I recieved my Master's of Secondary Math Education from the University of Missouri, St. Louis.  
    Currently, I am pursuing my Education Leadership Master's degree from UMSL.  Hopefully in a few years I serve as a school leader in a secondary school.
    At Gateway, I am involved with Cultural Day, our annual celebration of our students' diverse identities, and for several years I was a mentor for Gateway's robotics team.  I currently work with Ms. Kathryn Coleman  to lead the Show Me Costa Rica Project at Gateway STEM where we create experiential learning opportunities for students to study biology and Costa Rican culture in Costa Rica.  Our students learn entrepreneurship skills, public speaking skills, and gain international travel experience throughout the ten-month program.
