Danielli Costa

    I graduated from the University of North Texas - Denton (Class of 2011) and have a B.S. in Mathematics. I teach Mathematics (Precalculus, Precalculus Pre-AP and AP Statistics) here at TJ. This was my first school to work at. Highlights include: cover of North Texan (UNT alumni magazine) on a feature about UNT's College of Education, picture on the wall at Matthew's Hall (where the office of the College of Education is in Denton), and teacher of the year at TJ for 2014-2015. My classroom is a collaborative, challenging and respectful environment, where ideas are appreciated and shared with a growth mindset.
