I have been an elementary teacher for 20 years, mostly in Christian schools in NY and FL but spent a few years covering middle and high school math, for a teacher who had left. I am a 5th grade classroom teacher this year, my second year in s public charter school in Clearwater, FL, and realized last year when I went back to elmentary, teaching a combined 4th and 5th grade class that I need to sharpen the saw in math. By the way, that's my 6 week old grandaughter. 🙂
