Welcome to my third grade classroom! My name is Mrs. Erinn Tredo, and this is my eleventh year teaching in the Massena Central School District.  I previously taught first grade for nine years, and am on my second year of teaching third grade at Jefferson Elementary School.  This year, our third grade class name is Tredo's Time Warped Rebels, which was chosen to celebrate our District Attendance Initiative this year. On this page, you will find information such as classroom expectations, spelling lists, contact info, and links to frequently visited classroom sites. Please feel free to contact me at any time at [email protected].  Thank you for visiting my classroom site!   i-Ready 3rd Grade Wonders Spelling Lists and Outlines
