Welcome to math with Mrs. Gruebling! I graduated from the University of Northern Iowa with a BS in Mathematics Education in 2004. I then went on to earn a Masters of Education from the University of LaCrosse in 2007. I started teaching math in 2005 and have taught a wide array of levels ranging from General Math through AP Calculus, including 8th grade Geometry. I have taught mathematics in various different school districts, but I began teaching at Grafton HS in 2015. My course load currently includes Honors Geometry,  Pre-Calculus, and AP Calculus AB. My passion lies in teaching high school math and I work very hard to encourage student success in the courses I teach. I am available for help after school in room 228 or during BHT.
