Mrs. Costello is a great teacher and person. She was able to adjust her style to accommodate the various learning styles of each child. Outside of the classroom, Mrs. Costello was involved with the sports teams and even hosted a dinner at her house for the entire basketball team. She has the unique ability of being able to be kind and funny while at the same time, being authoritative and helpful. Nothing but the best memories of being Mrs. Costello's classroom!

I heard that Mrs. Costello was a great teacher last year. Not so this year. Not helpful, not understanding, slightly disrespectful. Some of my friends refer to her as "The Yeti" because of our utter disdain for her. Spanish was very easy for me last year; not so this year. I simply can't comprehend her teaching style.
