Hi, I’m Cheryl Knowles. I’m a first grade teacher at Cardinal. I grew up in Warwick, Rhode Island. I graduated from Rhode Island College with a B.S. in Elementary Education/ Special Education. I have a Masters degree in Literacy from George Mason University.  I’ve been teaching in Arlington since 1999. I was a second grade teacher for 7 years at Barcroft Elementary. I taught first grade at McKinley Elementary for 14 years. I’ve been teaching at Cardinal since 2021. When I’m not teaching, I like to travel back to New England to spend time with my nephews, my niece, and my extended family.  I am a huge Boston sports fan! I love watching sports, traveling with friends, yoga, going to the beach, and finding fun books to read!
