I'm Mr. Ethier, former math teacher and cross country coach at Mounds Park Academy. I used a variety of activities to help my students learn math. I also have a unique sense of humor which I often share with them. My personal history is rather unique as well. My hobbies include astronomy and flying my drones. I am also the author of the gradebook software Gradekeeper and apps like Spirolaterals and a simple game called Cushion Caroms.
