John Greenacre

Welcome to Mr. Greenacre's webpage!

I am entering my 12th year teaching and fifth year at Tex Hill.  For the 2021-22 school year, I will be teaching Algebra and 8th Grade Math.  Along with teaching, I coach the 7th grade boys' basketball Go Team and for the boys' track team. I also sponsor the Comic Book Club and am a member of the PTSA.  A couple of years back, I was Santa Claus in Tex Hill's production of the "Elf, Jr." musical! I love playing and beating my son at mini-golf and have coined myself "Tex Hill Tiger Woods"!

I am originally from Illinois but have also lived in Maine and Wisconsin. I am a proud two-time graduate of Illinois State University. Go Redbirds! My wife, Veronica, and I just got married in November on the Riverwalk. Our 7th grader loves to play the trumpet and is currently in basketball and tennis. This summer, we made a road trip through New Mexico and Colorado where we hiked a mountain in Boulder, went to a Rockies game in Denver, hung out with aliens in Roswell and rode the tram up Sandia Peak in Albuquerque.  We finished our family vacation in Arlington by celebrating our son's 12th birthday with an awesome concert rocking out with Weezer, Fall Out Boy & Green Day!!

I look forward to having an incredible school year and leading my students to great success.  It's always a great day to be a Tiger!

*Tutoring times fluctuate througout the year (see Announcement, Google Classroom or email for times)*

**Google Classroom links will be emailed to both parents and students in August.  I will not be posting the codes on this webpage.  If you have not received the GC links, please email ASAP so I can send you the code.**

***If you are going to join my REMIND to receive daily text message updates, please make sure you choose the correct class. Since I am teaching both Algebra and 8th Grade Math, I have two separate REMIND classes.  Be sure to choose the correct one when signing up.  If you are unsure, you can email me with your child's name and I can let you know which class your student belongs.***

****Be sure to download and read the Syllabus for your child's class. The syllabus gives an overview of what TEKS will be covered throughout the school year.****
