• My name is Heidi Brennan. I graduated from Tarleton State in 2012. I have two sons, ages 19 and 13. I am looking forward to exploring the wonderful world of math with your students this year. I will be teaching Geometry, Algebra 2, and Statistics. My goal is to connect my content area with real world experiences, to show students that even though they may not always use a concept directly, math is infused into every part of our lives.
