John Greenacre

Welcome to Mr. Greenacre's webpage!

I am entering my 13th year teaching and sixth year at Tex Hill.  For the 2022-23 school year, I will be teaching Algebra and 8th Grade Math. I also coach the 8th grade boys' basketball Go Team and long distance runners for the track team. I sponsor the Comic Book Club and am a member of ATPE and PTSA.  A couple of years back, I was Santa Claus in Tex Hill's production of the "Elf, Jr." musical and reprised the role for last year's "Candy Cane Lane".

I am originally from central 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, is a surgery coordinator for UT-Health and is currently attending LSUA. Go Generals! Our 8th grader, Jacob, is a member of NJHS, plays the trumpet for the Honors Band and participates in basketball, tennis & track. Go Tigers! This summer, my wife and I took a cruise and visited Puerto Rico, St. Thomas, St. Maarten, British Virgin Islands and Miami. While we were sailing the seas, our son was taking an Alaskan cruise with his grandparents. After our vacations, we danced along with the Blue Man Group at the Tobin Center, rocked out with Franz Ferdinand in Austin and celebrated the end of summer break with Jacob's 13th birthday party!

Last year, 100% of my Algebra students passed the EOC with 87% of them earning Mastery distinction. The 8th Grade Math students finished second in the district for STAAR testing, the first time Tex Hill 8th graders accomplished this feat. I look forward to building from that success and having an incredible school year. It's always a great day to be a Tiger!

*Tutoring times will fluctuate throughout the year due to my coaching commitments (see Google Classroom OR send me a Remind or email for times should you have questions)*

**Google Classroom links will be given to students in August. I will not be posting the codes on this webpage. Google Classroom access and participation is mandatory and necessary for the success of all students.**

***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 to.***

****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 and the necessary requirements in order to move on to high school.****

  • TI NSpire Calculator (Amazon link)

    TI-NSpire CX II is the calculator we will be using this year AND in high school. You are not required to purchase one but it is the same calculator used at Johnson HS so if you can purchase and use it at home now, the better off you'll be when you get to 9th grade.

  • STAAR Redesign for 2023

    STAAR will be changing for 2023. At least 25% of the exams will now be open-answer questions (meaning, not multiple choice). Please read the link from TEA explaining the redesign.
