My name is Mariana Cortez, and  I am a 6th and 7th grade math teacher at Armstrong Middle School.  This will be my 15th year here at Armstrong.  I graduated from the University of Texas at Dallas.  I have a 3 year old son, an 8 year old daughter, an 18 year old stepson, and a 21 year old stepdaughter.  I enjoy spending time with my family and listening to music.  I love teaching math and helping everyone reach their true potential!
