Student: "Thank you for giving me good grades on my report card!"
Me: "You don't have to thank me, you worked hard for them."
Student: "But you help me understand things I don't get, so thank you."
And I had this conversation with more than one student.
Their next report card may not be as great as this one because I would like to keep them as 5th graders for next year. :) Seriously, they are a wonderful group of students. They've been with me through the ups and downs of my first year of teaching. I will never forget them.
