Welcome to Miss. Costello's 5th grade math class! I am very excited for our 2019-2020 school year and can't wait to get to know each and every one of my students.
I was born and raised in New York and moved out to Arizona to attend Arizona State University, where I completed my Bachelor of Arts degree in Elementary Education.
I enjoy spending time with my friends and family and like any New Yorker, catching a Yankees game from time to time. I find teaching to be the most rewarding career, and take a great deal of pride in my work. I'm excited to embark on the journey that this new school year will bring. Go Cardinals!
